GENERAL DESCRIPTION
The universal codec combines two high resolution bidirectional analog channels with a DSP in a single chip. Besides the analog interfaces the PCD5096 includes two digital interfaces: an I2C-bus interface allowing an external microcontroller to program the chip, and a 4-wire serial interface compatible with IOM-2 and with DTAM speech compression ICs.

FEATURES
• Applications in digital terminal equipment featuring line interface and/or voice functions
• Digital signal processor performing echo cancellation, codec functions and dial tone detection
• Two independent receive and transmit channels
• Independent programmable gain for all analog inputs and outputs
• Programmable filter correction functions
• Flexible configuration of all functions
• IOM-2 serial data interface (slave mode only)
• Serial data interface to DTAM speech compression ICs
• 400 kHz I2C-bus slave interface (four I2C-bus subaddresses)
• Codec compatible with G.714 CCITT specification
• PCM A-Law/u-Law (G.711 CCITT) and 16-bit linear data
• Dual differential inputs and outputs performing the following functions:
   – Line interface connection
   – Loudspeaker, speaker phone (hands-free)
   – Earpiece, microphone (handset)
• Peripheral interface: two I/O pins
• Separate ringer function
• Tone and ringer generator
• Conference call
• QFP44 package
• Low voltage (2.7 to 3.6 V)
• Low power consumption.
