The VSC7716 device is a transimpedance amplifier (TIA) for GE-PON

ONU and OLT applications. 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.
