| ML7005 - DTMF Transceiver |
|
The ML7005 is a multi-functional DTMF transceiver LSI with built-in a DTMF signal generator, a DTMF signal receiver, a call progress tone generator, a call progress tone detector, and a FAX (FX) signal detector.
Each functional block can be controlled by an external MCU via a 4-bit processor interface. The ML7005 does not contains a modem. However, the DTMF system data transmission is possible at less than 66 bps by setting the DTMF receiver to the high-speed detection mode. The ML7005 operates with low-power consumption and is suitable for remote control systems, especially for ACR (Automatic Cost Routing) controllers. |
