UCB1510

( DataSheet : www.DataSheet4U.com ) UCB1510 AC97 digital modem codec Rev. 01 — 4 February 2000 Preliminary specification 1. 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. 2. Features s 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 s AClink (rev 2.1) interface with secondary codec support s 3.3 V supply voltage and built in power saving modes make the UCB1510 optimal for portable and battery powered applications s 5 V tolerant interface for motherboard/PC add on s Maximum operating current 25 mA s 8 general purpose IO pins for line interface control s Interrupt detection driven wake up sequence for ring detect s Low cost 12.288 MHz crystal c c 3.
