FUJITSU MICROELECTRONICS DATA SHEET DS04-29138-1E ASSP Spread Spectrum Clock Generator MB88182 DESCRIPTION MB88182 is the multi-output clock generator for EMI (Electro Magnetic Interference) reduction. The peak of unnecessary radiation noise (EMI) can be attenuated by making the oscillation frequency slightly modulate periodically with the internal modulator. It is possible to set the frequency in the built-in register using the I2C bus that can vary depending on the application. FEATURES * Built-in PLL : 3 Without spread-spectrum function : 1 (PLL) With spread-spectrum function : 2 (SSCG1, SSCG2) * Clock output pins : 5 pins CLK1 : Clock output when setting to CLK1 (PLL). CLK2 : Clock output when setting to CLK2 (SSCG1) . CLK3 : Clock output when setting to CLK3 (SSCG2) . CLK4 : Clock output when setting to CLK4 (SSCG2) . Note: It is not possible to output CLK3 and CLK4 at the same time. CKREF : Buffered output for CKIN clock. * Power down pins : 5 pins XPD1 : Control the stop state of PLL and the CLK1 output. XPD2 : Control the stop state of SSCG1 and the CLK2 output. XPD3 : Control the stop state of the CLK3 output. XPD4 : Control the stop state of the CLK4 output. Note: Halting both CLK3 and CLK4 stops operating the SSCG2. Control the stop state of the CKREF output.

The latch-up may cause components to burn out because the power supply current increases significantly. Make sure that the maximum ratings are not exceeded while the device is being used. (2) Handling unused pins Leaving unused input pins unconnected may cause a malfunction. Handle unused pins by connecting to a pullup or pull-down resistor. (3) Power supply pins Ensure that the impedance of the connection from the power supply source to the power supply pins on the device is as low as possible. We recommend connecting electrolytic capacitor (about 10 F) and the ceramic capacitor (about 0.01 F) in parallel between power supply and GND near the device, as a bypass capacitor. 8 DS04-29138-1E MB88182 BLOCK DIAGRAM Power down control XPD4 CLK4 SSCG2 XPD3 CLK3 Oscillates when setting to the enable side Setting to CLK4 SCL Setting to CLK3 SDA I2C circuit Setting to CLK2 Setting to CLK1 XPD2 XPD1 CKIN SSCG1 PLL CLK2 CLK1 CKREF XPDREF ENS DS04-29138-1E 9 MB88182 PIN SETTING ENS Modulation enable setting ENS Modulation 0 No modulation 1 (2.6 V) Modulation When setting 0 to the ENS pin, the spectrum will not spread.

XPD Power down setting XPDREF XPD1 XPD2 XPD3 XPD4 0 CKREF is fixed to the output "L". 1 (2.6 V) CKREF is the clock output. 0 PLL1 is in the power down state. CLK1 is fixed to the output "L". 1 (2.6 V) PLL1 and CLK1 are in operation. 0 SSCG1 is in the power down state. CLK2 is fixed to the output "L". 1 (2.6 V) SSCG1 and CLK2 are in operation. 0 CLK3 is fixed to the output "L". 1 (2.6 V) SSCG2 and CLK3 are in operation. 0 CLK4 is fixed to the output "L". 1 (2.6 V) SSCG2 and CLK4 are in operation. The pin in XPDREF, XPD1, XPD2, XPD3 and XPD4 is connected to the pull-up resistor. However, the pull-up resistor is cut off during "0" input. When both XPD3 and XPD4 are "0", SSCG2 is in the power down state. 10 DS04-29138-1E MB88182 SETTING REGISTER <Memory map> Setting register for CLK2, CLK3, CLK4 (All registers have the same configurations.)

When in reading : Undefined Remarks bit0 to 5 M divider setting (6-bit) Selectable in the range of 3 to 52 bit6 to 10 N divider setting (5-bit) Selectable in the range of 3 to 31 bit11 to 15 K divider setting (5-bit) Selectable in the range of 1 to 32 bit16 to 19 Charge Pump setting (4-bit) bit20 to 25 VCO Gain setting (6-bit) bit26 Output drive setting 0 : Ability small, 1 : Ability large bit27 Slewing rate setting 0 : Slewing rate low, 1 : Slewing rate high bit28 to 31 Invalid bit Charge pump current setting due to internal oscillation frequency and M divider setting Gain setting due to internal oscillation frequency When in writing : The written data is ignored. When in reading : Undefined Note: The bit's initial value in a register is undefined. Therefore, if the power down of clock output is released before the register setting, the clock is output with settings unintended. The power down of the clock output for CLK1, CLK2, CLK3 and CLK4 should be released after setting to registers. DS04-29138-1E 11 MB88182 <Frequency setting> When setting each divider parameter of the oscillator to a register, the output frequency can be set. Internal oscillation frequency and output frequency can be calculated with following formula: Internal oscillation frequency (fvco*) = Input frequency (fin) x M/N * : Please set the fvco range from 16 MHz to 168 MHz. Output frequency (fout*) = fvco/K * : Please set the fout range from 8 MHz to 100 MHz. Set the output frequency to 8 MHz to 50 MHz for CLK3 and CLK4 setting registers when VDP is 1.8 V 0.15 V. (Setting example) fin : 19.2 MHz, fout : 29.6 MHz M divider parameter : 222 ( = 0DEH) , N divider parameter : 144 ( = 090H) , K divider parameter : 1 ( = 01H) (19.2 x 222 / 144) / 1 = 29.6 (MHz) (fvco : 19.2 x 222 / 144 = 29.6 (MHz) ) Note: The recommended setting value of the VCO gain and the M divider depends on the internal oscillation frequency. Also, the recommended setting value of the Charge Pump depends on the setting values of the VCO gain and the M divider. Please confirm the recommended value with the Fujitsu Microelectronics support tool. Contact the sales representatives for details on the support tools. <Modulation frequency setting> Modulation frequency can be set by writing L divider parameter to the register. The average of modulation frequency can be calculated with following formula: Input frequency 266 x L (L = 1, 2, 3, 4, 5, 6, 7, 8) (Setting example) fin : 19.2 MHz 19.2 / (266 x 6) x 1000 = Approximately 12.0 (kHz) bit30 bit29 bit28 L divider parameter 12 0 0 0 8 0 0 1 1 0 1 0 2 0 1 1 3 1 0 0 4 1 0 1 5 1 1 0 6 (Recommended value) 1 1 1 7 DS04-29138-1E MB88182 <Modulation rate setting> Modulation rate can be selectable from no modulation, 0.25%, 0.50%, 0.75%, 1.00%, 1.25%, 1.50%, 1.75%. bit43 bit42 bit41 Modulation rate setting 0 0 0 No modulation 0 0 1 0.25% 0 1 0 0.50% 0 1 1 0.75% 1 0 0 1.00% 1 0 1 1.25% 1 1 0 1.50% 1 1 1 1.75% <Charge Pump setting, VCO gain setting> Please refer and confirm the recommended value by our support tool.

The modulation period FMOD depends on the input frequency and changes between FMOD (Min) and FMOD (Max). Furthermore, the typical value of the electrical characteristics is equivalent to the average value of the modulation period FMOD. <Output slew rate (SR) > CLK1 (VDD - 0.2) V,(VDP - 0.2) V, (VDDE - 0.2) V CLK2 CLK3 CLK4 0.2 V tf tr Note: SR = (power supply voltage - 0.4) / tr, SR = (power supply voltage - 0.4) / tf <Cycle-cycle jitter (tJC = |tn - tn + 1|)> CLK1 CLK2 CLK3 CLK4 24 tn tn+1 DS04-29138-1E MB88182 <Output timing with XPDREF control> VIL XPDREF CKREF tP tRPD VIH XPDREF CKREF tROE <Lock-up time> CKIN VIH XPD1, XPD2, XPD3, XPD4 VIL tLK (lock-up time) CLK1, CLK2, CLK3, CLK4 If the power down control is performed on pins XPD1, XPD2, XPD3 and XPD4, the desired clock frequency will be obtained once the power down pin becomes at the "H" level and after the lock-up time tLK has passed at maximum. CKIN ENS VIH tLK (lock-up time) VIL tLK (lock-up time) CLK2, CLK3,CLK4 If the ENS pin setting changes during the normal operation, setting clocks CLK2, CLK3 and CLK4 will be output once the ENS pin level is decided and after lock-up time tLK has passed at maximum. Note: When the ENS pin setting is changed, the stabilization wait time is needed for the output clock from CLK2, CLK3 and CLK4 pins. During the stabilization wait time, the output frequency, output clock duty cycle, modulation frequency, and cycle-cycle jitter cannot be guaranteed. It is therefore advisable to perform processing such as cancelling a reset of the device at the succeeding stage after the lock-up time.

The device input part contains the CMOS inverter and the feedback resistor (1 M). The clock input via the coupling capacity operates near the threshold level of the CMOS inverter, therefore the current for the capacity connection clock input increases compared to the normal input.
