UTOPIA-LVDS Bridge for 1.6 Gbps Bi-directional Data

Transfers

— Two independent LVDS receiver serial ports for

1.0 General Description

optional 1:1 protection

The DS92UT16 is a flexible UTOPIA to LVDS Bridge device.

— Main and redundant LVDS transmit ports

The LVDS Bridge transparently transports the UTOPIA bus

— Loop timing capability enables LVDS recovered clock

over a high speed LVDS serial link. The device includes

to internally drive LVDS transmit clock

many reliability features such as an optional 1:1 protection

— Internal buffers allow maximum LVDS serial bit rate

and built in bit error rate checking.

independent of UTOPIA clock rate

The parallel interface is user programmable for maximum

flexibility. The user can choose between UTOPIA Level Level

2 ATM layer (master) of PHY layer (slave). The UTOPIA-

LVDS Bridge supports a special MPHY (multi-PHY layer)

operation mode. The MPHY operation supports up to 248

standard UTOPIA Level 2 PHY ports without adding external

circuitry.

n Programmable UTOPIA interface

— UTOPIA Level 2 up to 52 MHz

— ATM layer or PHY layer interface

— ATM layer interface can support up to 248 standard

Level 2 PHY ports with no additional external

circuitry. Configured as 31 MPHY’s, each with up to 8

sub-ports

— Supports extended cell size up to 64 bytes

— Supports 16- or 8-bit data buses with parity

n Embedded bidirectional, non-blocking flow control over

serial link for per MPHY back pressure

n No external memories required

The serial interface uses LVDS Serializer and Deserializer

technology. The 16:1 bit serialization allows conveying the

full-duplex parallel bus over two differential transmission

pairs. This enables low cost backplanes and cables. Cable

transmission length can be as long 16 meters.

The serial link carries Flow control information (back pres-

sure) in both directions. The Bridge device applies back

pressure on a per queue basis over the 31 internal FIFO

queues. In addition, the serial link includes an OAM (Opera-

tions and Maintenance) channel that does not detract from

link performance.

n Embedded OAM channel over serial link

— Remote Alarm/Status Indications

— Link Trace Label

— Embedded Control Channel with flow control for

software communication

— BIP16 based error performance monitoring

— In protected systems, the standby link OAM channel

is available for embedded communications and

performance/alarm monitoring

There are many applications where the UTOPIA-LVDS

Bridge simplifies designs. Box-to-box connections can use

DS29UT16 devices across cables. Access multiplexor appli-

cations can use the devices across a PCB backplane for

point-to-point and lightly loaded multidrop configurations.

n Multiple loop-back options

n Standard microprocessor interface (Intel and Motorola

compatible)

n IEEE 1149.1 JTAG port

n Temperature range: −40˚C to +85˚C

n CMOS technology for low power

2.0 Features

n 832 Mbps LVDS 16-bit serializer and deserializer

interface

— Suitable for cable, printed circuit board, and

backplane transmission paths

— 10m cable at max LVDS data rate and greater than

16m at min LVDS data rate

n LVDS transceiver section uses 3.3V power supply.

Digital UTOPIA section uses 2.5V power supply. All I/O

are 3.3V tolerant.

n 196 LBGA package, 15x15x1.37 mm, 1.0 mm ball pitch

— Embedded clock with random data lock capability for

clock recovery

— PRBS (x³¹+ x²⁸+ 1) based LVDS link BER test

facility
