Precision receiver delay improves data transmission

Victor Fleury

Abstract

The LTC1518/ LTC1519/LTC1520 family of high speed line receivers that reduce propagation delay changes to less than ±17% over production variations and temperature, is described.

Moving data from one board to another over a backplane places stringent requirements on channel-to-channel and part-to-part skew and delay. The propagation delay of typical CMOS line receivers can vary as much as 500% over process and temperature. In high speed synchronous systems where clock and data signal timing are critical, transmission rates must often be reduced to minimize the effects of ...
