73M2921 Datasheet Advanced Single Chip Modem

Manufacturer: TDK Corporation

Overview: DESCRIPTION The 73M2921 is a CMOS integrated circuit which provides all the modem “Data Pump” functions required to implement a V.22bis data modem.

General Description

The 73M2921 is a CMOS integrated circuit which provides all the modem “Data Pump” functions required to implement a V.22bis data modem.

It consists of a DSP (Digital Signal Processor) core with RAM and ROM data memory, ROM instruction memory, and register mapped input/output functions including timers, interrupts, Σ∆ ADC and DAC ports and Serial Data I/O.

Once the 73M2921 has been initialized, all call progress and modem handshaking is automatic.

Key Features

  • include a parallel interface control port between the host processor and the 73M2921. A synchronous serial data channel provides synchronizing clocks RXCLK and TXCLK from the modem pump to the controller. The 73M2921 contains an oscillator and power control features. The host controller.
