Product Summary
The STLC5048 is a monolithic fully programmable 4 channel CODEC and filter. The STLC5048 operates with a single +3.3V supply. The analog interface is based on a receive output buffer driving the SLIC RX input and on an amplifier input stage normally driven by the SLIC TX output. Due to the single supply voltage a midsupply reference level is generated internally by the device and all analog signals are referred to this level (AGND). The STLC5048 PCM interface uses one common 8KHz frame sync. pulse for transmit and receive direction. The bit clock is automatically detected between four standards: 1.563/1.544MHz, 2.048MHz, 4.096MHz, 8192MHz. The STLC5048 can be programmed via serial interface running up to 8 MHz. One interrupt output pin is also provided.
