SY89323L

Micrel, Inc. 3.3V DUAL DIFFERENTIAL LVPECL-TO-LVTTL TRANSLATOR Precision Edge® Precision ESdYg89e3®23L SY89323L FEATURES ■ 3.3V power supply ■ 1.9ns typical propagation delay ■ Maximum frequency > 275MHz ■ Differential LVPECL inputs ■ 24mA LVTTL outputs ■ Flow-through pinouts ■ Internal input resistors: pull-down on IN, pull-down and pull-up on /IN ■ Q output will default LOW with inputs open ■ Available in ultra-small 8-pin MLF® (2mm × 2mm) package BLOCK DIAGRAM Precision Edge® DESCRIPTION The SY89323L is a dual differential LVPECL-to-LVTTL translator. Because LVPECL (Low Voltage Positive ECL) levels are used, only +3.3V and ground are required. The SY89323L is functionally equivalent to the SY100EPT23L, but in an ultra-small 8-pin MLF® package that features a 70% smaller footprint. The ultra-small package and the dual gate design of the SY89823L make it ideal for applications that require the translation of a clock and data signal in a minimal space. The inputs are compatible with 10k and 100k input levels and any standard differential LVPECL input referenced to a VCC of 3.3V.
