OM4031T Digital post-detection filter for FSK data receivers

OM4031T 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. When operated from a 38.4 kHz external clock it can handle data rates of 600, .

OM4031T 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
