Infineon Technologies 

PEB 20321

PEF 20321

Overview

– Automatic synchronization in receive direction, automatic generation of

the synchronization pattern in transmit direction

– E/S/X bits freely programmable in transmit direction, may be changed

during transmission; changes monitored and reported in receive direction

– Generation/detection of loss of synchronism

– Bit framing with network data rates from 600 bit/s up to 38.4 Kbit/s

– Transparent Mode A

– Slot synchronous transparent transmission/reception without frame structure

– Flag generation, flag stuffing, flag extraction, flag generation

in the abort case with programmable flag

– Synchronized data transfer for fractional T1/PRI channels

– Transparent Mode B

– Transparent transmission/reception in frames delimited by 00H flags

– Shared opening and closing flag

– Flag stuffing, flag detection, flag generation in the abort case

– Error detection (non octet frame content, short frame, long frame)

– Transparent Mode R

– Transparent transmission/reception with GSM 08.60 frame structure

– Automatic 0000H flag generation/detection

– Support of 40, 391/2, 401/2 octet frames

– Error detection (non octet frame contents, short frame, long frame)

– Protocol Independent

– Channel inversion (data, flags, IDLE code)

– Format conventions as in CCITT Q.921 § 2.8

– Data over- and underflow detected

• Microprocessor Interface

– 32-bit PCI bus interface option, 33 MHz

– 32-bit De-multiplexed bus interface option, 33 MHz

– 68 channel DMA controller (64 for 32 serial channels, 4 for 2 LBI channels) with

buffer chaining capability

– Master 4-DWORD burst read and write capability

– Slave single-DWORD read and write capability

– Interrupt-circular buffers with variable sizes

– Maskable interrupts for each channel

• IOM®-2 Interface with on-chip C/I and monitor handlers

• Synchronous Serial Control (SSC) Interface

• 8-/16-bit Local Bus Interface (LBI)
