6. System Interfaces

6.1. SPI Control Interface

The controller interface to the Si32260/1 is a 4-wire

interface modeled after microcontroller and serial

peripheral devices. The interface consists of a clock

(SCLK), chip select (CS), serial data input (SDI), and

serial data output (SDO). In addition, the ProSLIC

devices feature a serial data through output (SDITHRU

8x8 mm package only) to support operation of up to 16

channels using a single chip select line. Each FXS port

occupies one SPI channel. The device operates with

both 8-bit and 16-bit SPI controllers.

6.2. PCM Interface and Companding

The Si32260/1 contains a flexible, programmable

interface for the transmission and reception of digital

PCM samples. PCM data transfer is controlled by the

PCM clock (PCLK) and frame sync (FSYNC) inputs as

well as the PCM Mode Select, PCM Transmit Start, and

PCM Receive Start settings.

The interface can be configured to support from 8 to

128

8-bit

time

slots

each

125 µs

frame,

corresponding to a PCM clock (PCLK) frequency range

of 512 kHz to 8.192 MHz. 1.544 MHz is also supported.

The Si32260/1 supports both µ-255 Law (µ-Law) and A-

law companding formats in addition to 16-bit linear data

mode with no companding.
