Product Summary
The MSM7578VM3-K is a 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, the device is particularly optimized for telephone terminals in digital wireless systems and ISDN systems. The MSM7578VM3-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
MSM7578VM3-K absolute maximum 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
MSM7578VM3-K features: (1)Single power supply: +5.0 V ±5%; (2)Low power consumption, Operating mode: 25 mW Typ. 47 mW Max. VDD = 5 V; Power down mode: 0.05 mW Typ. 0.3 mW Max. VDD = 5 V; (3)ITU-T Companding law; MSM7578H: m-law; MSM7579: A-law; MSM7578V: m/A-law pin-selectable; (4)Built-in PLL eliminates a master clock; (5)Serial data rate: 64/128/256/512/1024/2048 kHz 96/192/384/768/1536/1544/200 kHz; (6)Adjustable transmit gain; (7)Built-in reference voltage supply; (8)Directly drive a line transformer of 600 W; (9)The 16-pin DIP and 24-pin SOP package products provide pin compatibility with the MSM7508B/7509B; (10)The 20-pin SSOP package products have 1/3 the foot print of conventional products.
