Si3226/7 and Si3208/9

Dual ProSLIC® with DC-DC Controller

- Software-programmable parameters:

Description

- Ringing frequency, amplitude, cadence, and wave-

shape

The Dual ProSLIC is a family of low-voltage CMOS

devices that integrate both SLIC and CODEC

functionality into a single IC. In combination with a

linefeed IC (LFIC), they provide a complete two-

channel analog telephone interface in accordance

with all relevant LSSGR, ITU, and ETSI

specifications. The Dual ProSLIC devices (Si3226/7)

operate from a single 3.3 V supply and interface to

standard PCM/SPI or GCI bus digital interfaces. The

LFICs (Si3208/9) perform all high-voltage functions

and operate from a 3.3 V supply as well as high-

voltage battery supplies. The Si3208 is rated for –

110 V, and the Si3209 is rated for –135 V. The Dual

ProSLIC devices are available in a 64-pin thin quad

flat package (TQFP), and the LFICs are available in a

40-pin, quad flat no-lead package (QFN).

- Two-wire ac impedance

- Transhybrid balance

- DC current loop feed (10–45 mA)

- Loop closure and ring trip thresholds

- Ground key detect threshold

- Loop or ground start operation

- Smooth polarity reversal

- DTMF generator/decoder

- A-Law/µ-Law companding,

linear PCM

- PCM and SPI bus digital interfaces with program-

mable interrupts

- GCI/IOM-2 mode support

- 3.3 V operation

Features
