E2A0035-16-X0 ¡ Semiconductor MSM6882-3/6882-5 ¡ Semiconductor 2400/1200 bps Single Chip MSK Modem ThisMSM6882-3/6882-5 version: Jan. 1998 Previous version: Nov. 1996 GENERAL DESCRIPTION The MSM6882-3/6882-5 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:+3.6 V (MSM6882-3) +5 V (MSM6882-5) 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. Bit rate 2400/1200 bps CCIR Rec. 623 The modulation method can be selected from COS-FFSK and SIN-FFSK. Built-in crystal oscillation circuit. Package options: 22-pin plastic DIP (DIP22-P-400-2.54) (Product name: MSM6882-3RS) (Product name: MSM6882-5RS) 24-pin plastic SOP (SOP24-P-430-1.27-K) (Product name: MSM6882-3GS-K) (Product name: MSM6882-5GS-K) 1/15 ¡...
