Description

ST5090is a high performancelow power combined PCM CODEC/FILTER device tailored to implement the audio front-end functions required by the next generation low voltage/low power consumption digital terminals.

ST5090 offers a number of programmable functions accessed through a serial control channel that easily interfaces to any classical microcontroller.

The PCMinterfacesupports both non-delayed(normal and reverse) and delayed frame synchronizationmodes.

ST5090 can be configurated either as a 14-bit linear  or as an 8-bit compandedPC Mcoder.

Additionally to the CODEC/FILTER function,  ST5090 includes a Tone/Ring/DTMF generator, a sidetone generation,and a buzzer driver output.

ST5090 fulfills and exceeds D3/D4 and CCITT recommendations and ETSI requirements for digital handset terminals.

Main applications include digital mobile phones, as cellular and cordless phones, or any battery powered equipment that requires audio codecs operating at low single supply voltages
