The output settling time is sufficiently fast to meet GE-PON OLT receiver requirements but slow enough to pass GE-PON ONU traffic. The VSC7716 device is equipped with an optional photocurrent monitor pin to provide a means of monitoring continuous optical receive power for photodetector alignment and digital diagnostics. The device padout is optimized for standard 4-pin and 5-pin TO-46 packages and accomodates both PIN detector and Avalanche photodiode (APD) designs. A space-saving filter connection is provided for positive bias to the photodiode through a filter resistor to VCC. The VSC7716 device is available in bare die only.
