DESCRIPTION
Add R1 at end of part number for 7 inch (1K parts), R2 for 13 inch (2.5K
parts) Tape & Reel.
Date code format: “Y” or “YY” for year followed by “WW” for week.
Parts marked JNB for date codes prior to 4WW (prior to 2004).
Date code “YWW” or “YYWW” on underside of part.
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 V
CC
and V
REF
. The SD output is an open drain compatible with
CMOS and TTL.
The outputs produce standard PECL 100K voltage compensated levels.
