Product Summary
The MSM7578VGS-K is single-channel CODEC CMOS IC for voice signals ranging from 300 to 3400 Hz. The device contains filters for A/D and D/A conversion. Designed especially for a single-power supply and low-power applications, it is particularly optimized for telephone terminals in digital wireless systems and ISDN systems. The MSM7578VGS-K uses the same transmission clocks as those used in the MSM7508B and MSM7509B. The analog output signal can directly drive a piezoelectric type handset receiver.
Parametrics
MSM7578VGS-K absolute maxing ratings: (1)Power Supply Voltage VDD: 0 to 7V; (2)Analog Input Voltage VAIN: –0.3 to VDD + 0.3V; (3)Digital Input Voltage VDIN: –0.3 to VDD + 0.3V; (4)Storage Temperature TSTG: –55 to +150℃.
Features
MSM7578VGS-K features: (1)Single power supply: +5.0 V ±5%; (2)Low power consumption; (3)Built-in PLL eliminates a master clock; (4)Serial data rate: 64/128/256/512/1024/2048kHz; 96/192/384/768/1536/1544/200 kHz; (5)Adjustable transmit gain; (6)Built-in reference voltage supply; (7)Directly drive a line transformer of 600 W; (8)The 16-pin DIP and 24-pin SOP package products provide pin compatibility with the MSM7508B/7509B; (9)The 20-pin SSOP package products have 1/3 the foot print of conventional products; (10)Package options: 24-pin plastic SOP (SOP24-P-430-1.27-K).
