M21328 HD/SD and 2xHD-SDI Cable Driver The M21328 is a high-speed, low-power, low-jitter cable drivers. It is designed to drive serial digital video data through 75 coaxial cable typically used in SMPTE and DVB-ASI video applications. The M21328 cable driver is optimized for performance from 143 Mbps up to 2970 Mbps. It has selectable slew rates for SD-SDI and HD-SDI applications. The typical output rise/fall time of the M21328 is 100 ps for HD and 2xHD rates. It has a typical set slew rate of 600 ps at SD rates. The default output voltage swing is compliant with SMPTE 292M, 259M, 344M and 424M using a 750 1% resistor. The M21328 supports a maximum single ended output swing of 1600 mVp-p, when configured appropriately. The M21328 device is packaged in a new high performance 4x4 mm MLF package to simplify the PCB and reduce package parasitics with resulting improvements in Output Return Loss (ORL). It is available in an RoHS compliant package, that is backwards compatible with standard JEDEC SnPb processes. The M21328 is pin compatible with the GS2978. It will also fit the footprint of the GS1578/1578A, but with the added feature of an Output Disable control pin.

This device passes 2000V of ESD Human Body Model (HBM) testing. Tested per JESD22-C101. This device passes 500V of ESD Charged Device Model (CDM) testing. Tested per EIA/JESD78. This device passes 150mA of trigger current at 85C during Latchup testing. 1.6.2 Peak Reflow Temperature M21328G (RoHS compliant package): Peak reflow temperature is 260C per JEDEC standards. 1.7 Design Considerations See Digital Video Interfacing Application Note (212xx-APP-001-A) for guidance on the following: * Component Placement and Layout * Routing Considerations and Thermal Considerations The M21328 consumes less power than legacy devices, therefore the M21328 will contribute less thermal energy resulting in a lower operating temperature. 21328-DSH-001-E Mindspeed Technologies(R) Mindspeed Proprietary and Confidential 13 2.0 Functional Description 2.1 Features 2.1.1 HD-SDI and SD-SDI Slew-rate Selection The output slew rate of the M21328 is selectable to conform with the different SD-SDI, HD-SDI, and 2xHD specifications. With SD/HD = Low, rise/fall time is typically 100 ps. The slew rate will vary depending on the output matching network and connector used. With SD/HD = High, for standard definition (143 to 540 Mbps) applications, the rise/fall time is typically 600 ps, which is compliant with SMPE 259M and SMPTE 344M. 2.1.2 Output Amplitude Adjustment A resistor connected to RSET pin is used to set the single ended output amplitude swing. For SMPTE compliance, an external 750 1% resistor at RSET to AVDD is recommended for a swing level of 800mV within a tolerance that is less than 10% which meets SMPTE requirements. The output amplitude can also be adjusted to range from 500 to 1600 mVpp single ended using the following formula: Output Swing = (600/RSET) [RSET in k] (in mVpp, Single Ended) The actual swing is set as a function of the IC supply voltage, the external termination voltage and the limitations are shown in Table 2-1. In applications where a lossy matching or splitting networks are used, the M21328 offers additional gain of up to 1600 mVpp swings, so the output after the lossy network can be SMPTE compliant.

The M21328 uses external 50 input termination resistors to match 100 differential impedance transmission lines for improved system level performance. The M21328 recommended input circuits are shown in Figure 2-1 and Figure 2-2. Note that AC coupling is not required when the M21328 is driven by Mindspeed Broadcast video devices. Figure 2-1.

A typical output matching circuit is shown in Figure 2-3. The Output Return Loss (ORL) is dependent on many factors such as the value and type of components used, PCB layout, PCB trace lengths, and type of PCB di-electric, therefore, the recommendations in the figure below should be used as starting guidelines only. Different output matching network topologies and different component values will result in different ORL performance. The M21328 has SD-SDI and HD-SDI rise/fall times that are typically faster than the legacy cable driver devices but within the relevant SMPTE specification for additional margin in most designs. The faster output slew rate results in a more open eye. The actual maximum output of the part depends on the applied IC voltage as well as the external termination voltage for the load termination. The limitations are discussed in Section 2.1. Figure 2-3.

Power Pins Pin Name Pin # AVSS 3 Chip Ground Power AVDD 9 Positive Supply Power NC 5, 7, 8, 13, 14, 15, 16 Center Pad -- Table 2-4. Type Not Connected. Leave these pins floating. Do not connect to any supply, ground or logic level. Chip Ground NC Power High-speed Signal Pins Pin Name Pin # SDI/SDI 1, 2 SDO/SDO 12, 11 Table 2-5. Function Function Default Type Non-inverting and Inverting serial externally terminated inputs. -- I--High-speed Non-inverting and inverting serial unterminated data outputs to coaxial cable. -- O--High-speed Default Type Pull-up I--CMOS Pull-up I--CMOS Control Pins Pin Name Pin # SD/HD 10 Function Input control signal to change the output slew rate. SD/HD = High: Slow output slew rate for SD-SDI rate (143-540 Mbps). SD/HD = Low: Fast output slew rate for HD and 2xHD-SDI rate. DISABLE 6 A low disables the SDO/SDO outputs. A high enables the SDO/SDO outputs. NOTES: Internal pull-ups/pull-downs are 100 k. 21328-DSH-001-E Mindspeed Technologies(R) Mindspeed Proprietary and Confidential 17 Appendix A.1 Glossary of Terms/Acronyms BER Bit Error Rate CD Cable Driver CDA Cable Distribution Amplifier CML Current Mode Logic CMOS Complementary Metal Oxide Semiconductor DPLL Digital Phase Locked Loop DTV Digital Television DVB Digital Video Broadcast EMI Electro Magnetic Interference EQ Equalizer or Equalization GREEN Environmentally friendly HD High Definition HW Hardware IC Integrated Circuit ID Identifier I/O Input/Output MLF Micro Lead Frame package (also called QFN) PCB Printed Circuit Board ORL Output Return Loss RoHS Restriction of Hazardous Substances SD Standard Definition SDI Serial Digital Input SDO Serial Digital Output SE Single Ended SMPTE Society of Motion Picture and Television Engineers 21328-DSH-001-E Mindspeed Technologies(R) Mindspeed Proprietary and Confidential 18 A.2 Reference Documents A.2.1 External The following external documents were referenced in this data sheet. * Application Notes for Surface Mount Assembly of Amkor's MicroLeadFrame (MLF) Packages * Amkor Technology Thermal Test Report TT-00-06 (See http://www.amkor.com for detailed information) * SMPTE 292M, SMPTE 259M, SMPTE 344M * ESI TR101 891 DVB Asynchronous Serial Interface (ASI) 21328-DSH-001-E Mindspeed Technologies(R) Mindspeed Proprietary and Confidential 19 www.mindspeed.com General Information: Telephone: (949) 579-3000 Headquarters - Newport Beach 4000 MacArthur Blvd., East Tower Newport Beach, CA 92660 (c) 2007-2009 Mindspeed Technologies(R), Inc.
