GENERAL DESCRIPTION
The MSM7584C is a CMOS IC developed for use with digital cordless telephones. The device provides a π/4 shift QPSK modem function and a CODEC function which performs transcoding between the voice band analog signal and 32 kbps ADPCM data.
The MSM7584C is ideal for use in a handset of the PHS (Personal Handyphone System).
FEATURES
(π/4 Shift QPSK Modem)
? Built-in root Nyquist filter (a (rolloff rate) = 0.5) for the baseband limiter
? Differential I and Q analog outputs
? The DC offset and gain can be adjusted with respect to the differential I and Q analog outputs
? Completely digitized π/4 shift QPSK demodulator system
? Input IF signal frequency of 1.2 MHz or 10.8 MHz is available.
? Built-in A/D converter for RSSI detection
(ADPCM CODEC)
? ADPCM : ITU-T Recommendations G.721 (32 kbps)
? Transmit/receive full duplex capability
? PCM interface code format: selectable between m-law and A-law
? Built-in transmit/receive mute function and transmit/receive programmable gain setting function
? Side tone path formation and level adjustment capabilities
? Built-in DTMF tone and other tones
? Built-in VOX function
? Built-in speech recording/playing interface
? Built-in 150 W driving OP AMP
? Built-in various analog switches
(Common)
? Single 3V power supply (VDD: 2.7 V to 3.6 V)
? Mode setting through serial interface
? Low power consumption
When the modem unit is operating : 13 mA Typ. (VDD = 3.0 V)
When the ADPCM CODEC unit is operating : 7 mA Typ. (VDD = 3.0 V)
When in the power down mode : 0.03 mA Typ. (VDD = 3.0 V)
? Package:
80-pin plastic TQFP (TQFP80-P-1212-0.50-K) (Product name : MSM7584CTS-K)
