1 Add R1 at end of part number for 7 inch (1K parts), R2 for 13 inch (2.5K
parts) Tape & Reel.
2 Date code format: “Y” or “YY” for year followed by “WW” for week.
3 Parts marked JNB for date codes prior to 4WW (prior to 2004).
4 Date code “YWW” or “YYWW” on underside of part.
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.
