LQFP64 package
PCM in HI-Z mode
Due to the single supply voltage a proper mid
supply reference level is generated internally by
the device and all analog signals are referred to
this level (AGND).
The PCM interface uses one common 8 kHz
frame sync. pulse for transmit and receive
direction. The bit clock can be selected between
four standards: 1.536/1.544 MHz, 2.048 MHz,
4.096 MHz, 8192 MHz. 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 pin-strap 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
4 MHz.
One interrupt output pin is also provided.

Description
The STLC5046 is a monolithic programmable 4
channel codec and filter. It operates with a single
+3.3 V supply.
The analog interface is based on a receive output
buffer driving the SLIC RX input and on an
amplifier input stage.
