Description
The MT3370BS is a high-performance DTMF receiver that decodes all 16 tone pairs into a 4-bit binary code. It is suitable for end-to-end signaling and incorporates an AGC for wide dynamic range. The device provides an early steering (ESt) logic output to indicate DTMF signal detection and requires external software guard time to validate the DTMF digit. The MT3370BS can be used with a crystal or a ceramic resonator and a power-down option is provided.
Specifications and features
- Wide dynamic range DTMF receiver with 50 dB range
- Call progress detection via cadence indication
