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

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.)
• Operating temperature from −10 to +70 °C.

APPLICATIONS
• Telemetry data receivers
• RF security systems
• Low-bit-rate radio data links
• Paging applications of UAA2080 and UAA2082 with software decoding.
