MSM6948GS-K数据手册OKI中文资料规格书

描述 Description

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:
18-pin plastic DIP (DIP18-P-300-2.54) (Product name: MSM6948RS)
24-pin plastic SOP (SOP24-P-430-1.27-K) (Product name: MSM6948GS-K)
