1 FEATURES 2 GENERAL DESCRIPTION
PCD5096
· 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. 4 ORDERING INFORMATION TYPE NUMBER PCD5096H
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. This programmable serial interface offers up to 14 channels and is capable of handling 8-bit (A-law) or 16-bit (linear PCM) data packages, or any combination of them. It opens the scope for a wide application area, for example in combination with the PCD5093H DECT baseband chip for digital cordless business applications. Several PCD5096s can be connected together for small switching systems (PABX) offering a combination of corded and cordless functionality. Besides the basic functions like echo cancellation for two channels the on-chip DSP provides all necessary functions such as conference call and DTMF. 3 APPLICATIONS
The PCD5096 is designed for the telecommunications market and is targeting small business and residential systems offering a two-line interface or a one-line interface combined with hands-free speaker phone. Specific applications are detailed in Chapter 12.
