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 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.
Two PCM port are provided: the channels can be connected to port A or/and B.
Device programmability is achieved by means of several registers and commands allowing to set the different parameters like TX/RX gains, line impedance, transhybrid balance, equalization (frequency response), encoding law (A/µ), time slot assignment, independent channels power up/down, loopbacks, PCM bits offset.
The STLC5048 can be programmed via serial interface running up to 8 MHz.
One interrupt output pin is also provided.
A GUI interface is also available to emulate and program the coefficients for impedance synthesis, echo cancelling and channel filtering.
