The AZ88943 is a limiting post amplifier usable at data rates up to 2.5Gbps. It is ideal for use as a post
amplifier following a transimpedance amplifier.
The AZ88943 contains a programmable signal detect function to determine when the input signal is present.
This information can be used with the /EN input pin to disable the output under loss of signal conditions. The detect
threshold can be set with a resistor divider between VCC and VREF. The SD output is an open drain compatible with
CMOS and TTL.
The outputs produce standard PECL 100K voltage compensated levels.
