Connect to GND. 2, 3 SDI, SDI Analog Input Serial digital differential input. 4GAIN_SEL Not Synchronous Input Input Sensitivity Control. When LOW the sensitivity is 800mV. When HIGH the sensitivity is 400mV. Includes an internal pull-down resistor. 5, 6 AGC, AGC Analog – External AGC capacitor. Connect pin 5 and pin 6 as shown in the Typical Application Circuit on page 16. 7BYPASS Not Synchronous Input Core Bypass control signal input. Forces the Equalizing and DC RESTORE stages into bypass mode when HIGH. No equalization occurs in this mode. Includes an internal pull-down resistor. |
