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.
