MSM7584D  
p/4 Shift QPSK MODEM/ADPCM CODEC  
GENERAL DESCRIPTION  
The MSM7584D is a CMOS IC developed for use with digital cordless telephones. The device  
provides a p/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  
(p/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 p/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.726 (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 (V : 2.7 V to 3.6 V)
