[LAPIS SEMICONDUCTOR]

GENERAL DESCRIPTION
The ML7041 is a single-channel full duplex CODEC LSI device which performs mutual transcoding between the analog voice band signals ranging from 300 to 3400 Hz and the 64 kbps PCM serial data. Provided with such functions as DTMF Tone generation, transmit/receive data gain control, side-tone path, and low-dropout regulator, the ML7041 is best suited for telephone terminals in digital wireless systems.

FEATURES
• Single 3 V power supply VDD: 2.4 to 3.3 V
• Coding format: PCM -law/PCM A-law/14-bit linear mode selectable
• PCM interface timing: Long frame synchronous timing/short frame synchronous timing selectable
• Transmit/receive full-duplex operation
• Serial PCM transmission data rate: 64 to 2048 kbps
• Low power consumption
   Operating mode: 15 mW typ. (VDD = 3.0 V)
   Power-down mode: 3 W typ. (VDD = 3.0 V)
• Master clock frequency: 2.048 MHz (compatible with PCM shift clock)
• Analog output stage
   100 mW (differential type) amplifier output for driving receiver speaker:
   Capable of driving an 8 Ω load.
   6.6 mW (single type) amplifier output for driving earphones speaker:
   Capable of driving a 32 Ω load.
• Built-in two low-dropout regulators (150 mA X 2)
• Built-in four general purpose drivers (150 mA X 4)
• Transmit/receive mute, transmit/receive programmable gain control
• Built-in side tone path
• Built-in DTMF tone generator
• Transmit slope filter selectable
• I2C bus interface (MCU interface)
• Built-in transmit voice signal detector
• Package: 48-pin plastic TQFP (TQFP48-P-0707-0.50-K) (ML7041 TB)
