MSM6948-3 General Description


The MSM6948-3 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.
