APS3606D Active Splitter for Digital CATV Set-Top Boxes ADVANCED PRODUCT INFORMATION - Rev 0.0 FEATURES * Single Input, Triple Output Design * High Linearity, Low Distortion Outputs Support Digital Video Tuner Applications * Wideband Operation: To Above 1 GHz 4.5 dB Typical Noise Figure at 53 dB Gain * * Extended Dynamic Range Gain Control, Independent for each RF path * Single +5 V Supply * Balanced 75 Ohm Inputs/Outputs * RoHS Compliant/Lead Free AP S3 60 6D APPLICATIONS * CATV Digital only Set-Top Boxes with Multiple Tuners S29 Package 28 Pin QFN 5 mm x 5 mm x 1 mm PRODUCT DESCRIPTION This active splitter from ANADIGICS accepts a balanced RF input in the 50 MHz to 1.1 GHz frequency range and provides three balanced RF outputs with minimal degradation in signal quality. The singlepackage surface mount device amplifies the input signals using highly linear, low noise amplification stages, and couples the amplified signal to three separate output paths that can drive video tuner inputs. effects on each output signal. Requiring only a single +5 Volt supply, the active splitter design is implemented using the ANADIGICS GaAs MESFET process. The RoHS-compliant surface mount packaging makes the device ideal for use in today's multiple-tuner set-top boxes for Cable TV. Each of the RF paths includes independent Gain Control. The overall linearity of each path is maintained across a wide gain range, ensuring low distortion AGC1 AGC2 AGC3 RF1OUT+ RF1OUTRFIN+ RFIN- RF2OUT+ RF2OUTRF3OUT+ RF3OUT- Figure 1: Functional Block Diagram 12/2007 GND GND GND GND GND GND GND APS3606D 28 27 26 25 24 23 22 GND RFIN+ 3 19 VID1OUT- GND 4 18 GND RFIN- 5 17 VID2OUT+ GND 6 16 GND AGC VID1 7 15 VID2OUT- 8 9 10 11 12 13 14 GND 20 VID3 OUT- 2 GND GND GND VID1OUT+ VID3 OUT+ 21 AGCVID3 1 AGCVID2 VCC Figure 2: Pinout (X-ray Top View) Table 1: Pin Description 2 PIN NAME DESCRIPTION PIN NAME DESCRIPTION 1 VCC Supply Voltage 28 BIAS1A RF1 Bias 2 RFIN+ RF Input (+) 27 GND Ground 3 N/C No Connection 26 RF1OUT+ RF1 Output (+) 4 RFIN- RF Input (-) 25 N/C No Connection 5 N/C No Connection 24 RF1OUT- RF1 Output (-) 6 AGC1 RF1 Gain Control Input 23 GND Ground 7 AGC2 RF2 Gain Control Input 22 BIAS1B RF1 Bias 8 AGC3 RF3 Gain Control Input 21 BIAS2B RF2 Bias 9 BIAS3A RF3 Bias 20 GND Ground 10 GND Ground 19 RF2OUT- RF2 Output (-) 11 RF3OUT+ RF3 Output (+) 18 N/C No Connection 12 RF3OUT- RF3 Output (-) 17 RF2OUT+ RF2 Output (+) 13 GND Ground 16 GND Ground 14 BIAS3B RF3 Bias 15 BIAS2A RF2 Bias ADVANCED PRODUCT INFORMATION - Rev 0.0 12/2007 APS3606D ELECTRICAL CHARACTERISTICS Table 2: Absolute Minimum and Maximum Ratings PARAMETER MIN MAX UNIT Supply Voltage (VCC) 0 +8 V AGC Input Voltage 0 +5 V RF Input Power (PIN) - +25 dBmV COMMENTS differential into 75 Stresses in excess of the absolute ratings may cause permanent damage.
