PCD5096

· 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.

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. PCD5096 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.
