STLC5048

Fully programmable four-channel codec and filter

Features

■ Fully programmable monolithic 4-channel

codec/filter

■ Single +3.3 V supply

TQFP64 (10x10x1.4mm)

■ A/m law programmable

■ Linear coding (16 bits) option

Description

■ PCM highway format automatically detected:

1.536 or 1.544 MHz, 2.048, 4.096, 8192 MHz

The STLC5048 is a monolithic fully programmable

4-channel codec and filter. It operates with a

single +3.3V supply.

■ Two PCM ports available

■ TX gain programming: 33 dB range; <0.01 dB

step

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 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 is automatically

detected between four standards:

■ RX gain programming: 42 dB range; <0.01 dB

step

■ Programmable SLIC input impedance

■ Programmable transhybrid balance filter

■ Programmable equalization (frequency

response)

■ Programmable time slot assignment

■ Digital and analog loopbacks

1.563/1.544 MHz, 2.048 MHz, 4.096 MHz,

8192 MHz.

■ SLIC control port static (16 I/Os),

dynamic (12 I/Os + 4 CS)

Two PCM port are provided: the channels can be

connected to port A or/and B.

■ Built-in test mode with tone generation, MCU

access to PCM data

■ 64 TQFP (10x10mm) package

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/m), time

slot assignment, independent channels power

up/down, loopbacks, PCM bits offset.

■ Programmable SLIC line current limitation

■ Programmable SLIC off-hook detection

threshold

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.
