MSM6948/6948V

1200 bps Single Chip MSK Modem

FEDL6948_6948V-02

Issue Data: Jun 8, 2005

GENERAL DESCRIPTION

The MSM6948/6948V is a single chip MSK (Minimum Shift Keying) modem which is fabricated by Oki’s low

power consumption CMOS silicon gate technology.

The demodulator receives the data to be transmitted (SD) synchronized with the transmit timing clock (ST)

generated by the on-chip clock generator. The signal, which is modulated by MSK method, is output.

The demodulator converts the received MSK signal to the received data (RD) by means of a delay detection

technique after limiting the band of the received MSK signal. This signal is input to the digital PLL and the

re-generated timing clock (RT) is output from the demodulator, synchronized with the RD.

FEATURES

•

Signal power supply: +5 V

On-chip SCF (Switched Capacitor Filter)

The transmit filter can be also used as voice splatter filter.

The receive timing re-generator has two different lock-in time performance options to be chosen from.

Built-in crystal oscillation circuit

Small number of external components for easy application

Wide application-wireless data equipment, MCA system

Low power consumption CMOS

Package options:
