SY89844U Datasheet Precision Lvds Runt Pulse Eliminator 2:1 Mux

Manufacturer: Micrel Semiconductor (now Microchip Technology)

Overview: SY89844U Precision LVDS Runt Pulse Eliminator 2:1 MUX with 1:2 Fanout and Internal Termination.

General Description

The SY89844U is a low jitter LVDS, 2:1 input multiplexer (MUX) optimized for redundant source switchover applications.

Unlike standard multiplexers, the SY89844U unique 2:1 Runt Pulse Eliminator (RPE) MUX prevents any short cycles or “runt” pulses during switchover.

In addition, a unique Fail-Safe Input protection prevents metastable conditions when the selected input clock fails to a DC voltage (voltage between the pins of the differential input drops below 100mV).

Key Features

  • Precision Edge®.
  • Selects between two sources, and provides a glitch-free, stable LVDS output.
  • Guaranteed AC performance over temperature and supply voltage:.
  • wide operating frequency: 1kHz to >1.5GHz.
