Description
www.DataSheet4U.com ARIZONA MICROTEK, INC. AZ88923 High-Speed Limiting Post Amplifier FEATURES Up to 2.5Gbps operation Differential PECL Inputs Differential PECL Outputs Open Drain TTL/CMOS LOS Output TTL/CMOS Enable Input High-Speed SiGe Process PACKAGE AVAILABILITY PACKAGE TSSOP 10 1 2 3 4 PART NUMBER AZ88923U MARKING AZ88 923 NOTES 1,2,3 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 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.
