Connect to GND. 2, 3 SDI, SDI Analog Input Serial digital differential input. 4 GAIN_SEL Not Synchronous Input CONTROL SIGNAL INPUT levels are LVCMOS/LVTTL compatible. (3.3V tolerant) Controls flat band gain. See Section 4.6. (Internal pull-down). 5, 6 AGC, AGC Analog – External AGC capacitor. Connect pin 5 and pin 6 together as shown in the Typical Application Circuit on page 16. 7BYPASS Not Synchronous Input Forces the Equalizing and DC RESTORE stages into bypass mode when HIGH. No equalization occurs in this mode. (Internal pull-down). |
