Product details

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. ).
