OM4031T Overview
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, 1200 and 2400 bits/s at an oversampling rate of 16.
OM4031T Key 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 ponents required
- Single supply voltage from 1.8 to 6.0 V
- Very low operating current (1.5 µA typ.)
- Operating temperature from -10 to +70 °C
