Description
The UCB1510 is a single chip, integrated mixed signal telecom codec that can directly be connected to a DAA and supports high speed modem protocols. The general purpose I/O pins provide programmable inputs and/or outputs to the system.
The UCB1510 has a serial AClink interface intended to communicate to the system controller. Both the codec input data and codec output data and the control register data are multiplexed on this interface.

FEATUREs
■ Sigma delta telecom codec with programmable sample rate, including digitally controlled input voltage level, mute, loop back and clip detection functions. The telecom codec can be directly connected to a Data Access Arrangement (DAA) and includes a built in sidetone suppression circuit
■ AClink (rev 2.1) interface with secondary codec support
■ 3.3 V supply voltage and built in power saving modes make the UCB1510 optimal for portable and battery powered applications
■ 5 V tolerant interface for motherboard/PC add on
■ Maximum operating current 25 mA
■ 8 general purpose IO pins for line interface control
■ Interrupt detection driven wake up sequence for ring detect
■ Low cost 12.288 MHz crystal

APPLICATIONs
■ Standalone modems
■ Integrated modems
■ Audio/Modem Riser (AMR) Cards
■ Mobile Daughter Cards (MDC)
