OM4031T - Digital post-detection filter for FSK data receivers

Datasheet Summary

Description

The OM4031T is intended for performance enhancement of FSK data receivers that do not have a built-in post-detection filter.

It contains a digital moving average filter to remove noise from the demodulated data.

Features

  • External clock frequency 30 to 80 kHz (typ. 38.4 kHz).
  • Supported data rates 600, 1200, 2400 and 4800 bits/s (typ. ).
  • Double bandwidth option (not for 4800 bits/s).
  • Schmitt-triggered inputs for optimum slope tolerance.
  • Enable input for power-down mode.
  • Open-drain output (3-state in power-down mode).
  • No external components required.
  • Single supply voltage from 1.8 to 6.0 V.
  • Very low operating current (1.5 µA typ. ).
