It 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. Due to the single supply voltage a proper midsupply reference level is generated internally by the device and all analog signals are referred to this level (AGND). The TQFP64 ORDERING NUMBER: STLC5046 PCM interface uses one mon 8KHz frame sync. pulse for transmit and receive direction. The bit clock can be selected between four standards: 1.536/1.544MHz, 2.048MHz, 4.096MHz, 8192MHz. Device programmability is achieved by means of 41 registers allowing to set the different parameters like TX/RX gains, encoding law (A/µ), time slot assignment, independent channels power up/down, loopbacks, PCM bits offset. Thanks to pinstrap option, the most significant of the above parameters can be set by hardware connection of dedicated pins. This allow to use this device also on line card without MCU on board. When pin strap option is selected different pins of the device will change their function (see pin description). In MCU control mode the STLC5046 can be programmed via serial interface running up to 4MHz. One interrupt output pin is also provided.
