High Speed Limiting Post Amplifier  
DESCRIPTION  
FEATURES  
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.  
Up to 2.5Gbps operation  
Differential PECL Inputs  
Differential PECL Outputs  
Open Drain TTL/CMOS  
LOS output  
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  
TTL/CMOS Enable input  
High Speed SiGe Process  
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.
