com Philips Semiconductors Preliminary specification Advanced modem/audio analog front-end FEATURES UCB1300 • 48 pin LQFP (SOT313) small body SMD package and low external component count results in minimal PCB space requirement • 12-bit sigma delta audio codec with programmable sample rate, input and output voltage levels, capable of connecting directly to speaker and microphone, including digitally controlled mute, loopback and clip detection functions • 14-bit sigma delta telecom codec with programmable sample rate, including digitally controlled input voltage level, mute, loopback 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 • Complete 4 wire resistive touch screen interface circuit supporting position, pressure and plate resistance measurements • 10-bit successive approximation ADC with internal track and hold circuit and analog multiplexer for touch screen read-out and monitoring of four external high voltage (7.
5V) analog voltages • High speed, 4 wire serial interface data bus (SIB) for communication to the system controller • 3.
3V supply voltage and built in power saving modes make the UCB1300 optimal for portable and battery powered applications • Maximum operating current 25 mA • 10 general purpose IO pins APPLICATIONS • Handheld Personal Computers, Personal Intelligent Communicators, Personal Digital Assistants • Smart Mobile Phones • Screen/Web Phones • Internet Access Terminal • Modems GENERAL DESCRIPTION The UCB1300 is a single chip, integrated mixed signal audio and telecom codec.
The single channel audio codec is designed for direct connection of a microphone and a speaker.
The built-in telecom codec can directly be connect...
