TC35821F 155 Mbps

SONET/SDH ATM Framer

the industry standard UTOPIA (Universal Test and Operations

Physical Layer Interface for ATM) level one or two interface.

Toshiba's TC35856F 155Mbps PCI-SAR and TC35853F 155

Mbps SAR are examples of SARs which can be used with

the TC35821F.

Features

• SONET STS-3c and STS-1/SDH STM-1

• 155.52Mbps PECL Serial Network Interface

• On-chip Clock Recovery

The TC35821F supports SONET standards STS-1 and

STS-3C. It contains a 155.52 megahertz (MHz) pseudo emit-

ter coupled logic serial line interface to the transceiver chips.

The device offers programmable section overhead (SOH)/

path overhead (POH) handling and operates internally at

19.44MHz/6.48MHz with a maximum 40 MHz cell-interface

operation. The TC35821F is designed in 0.6 micron CMOS

technology and operates on a single +5.0 volt power supply.

The TC35821F 155Mbps framer contains clock recovery

circuits, byte alignment and frame synchronization, frame

descrambling, frame overhead analysis, ATM cell synchroni-

zation, ATM cell header error correction and ATM cell payload

descramble functions. Its transmit functions include ATM cell

payload scramble, ATM header error correction (HEC) gener-

ation, frame overhead generation, frame assembly and frame

scrambling. In addition, access to the chip registers from the

central processing unit is available for conﬁguration, status,

diagnostics error counter and cell counter.

• Transmit Clock Synthesis

– 19.44MHz to 155.52 MHz

• UTOPIA Level-1 & 2 Interface

• 144-pin PQFP

• 0.6 micron CMOS, 5 volts

Description

The TC35821F is a single-chip 155.52 Megabits per second

(Mbps) framer chip for asynchronous transfer mode (ATM)

physical layer application. It can be used for network inter-

face card (NIC), switch and router applications.

The TC35821F offers cost-effective physical layer con-

troller solutions. In NIC applications, an ATM framer chip

used in conjunction with a transceiver on one side and a seg-

mentation and reassembly (SAR) chip on the other provides a

complete ATM solution. The interface to the SAR device is via

SRAM
