DESCRIPTION
The AZ88923 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 AZ88923 contains a programmable loss of signal detect function to determine when the input signal has been lost. This information can be used with the EN input pin to disable the output under LOS conditions. The detect threshold can be set with a resistor divider between VCC and VREF. The LOS output is an open drain compatible with CMOS and TTL.
The outputs produce standard PECL 100K voltage compensated levels.
