DS90CR481 / DS90CR482

48-Bit LVDS Channel Link SER/DES − 65 - 112 MHz

enhancement. To increase bandwidth, the maximum clock

rate is increased to 112 MHz and 8 serialized LVDS outputs

are provided. Cable drive is enhanced with a user selectable

pre-emphasis feature that provides additional output current

during transitions to counteract cable loading effects. Op-

tional DC balancing on a cycle-to-cycle basis, is also pro-

vided to reduce ISI (Inter-Symbol Interference). With pre-

emphasis and DC balancing, a low distortion eye-pattern is

provided at the receiver end of the cable. A cable deskew

capability has been added to deskew long cables of pair-to-

pair skew of up to +/−1 LVDS data bit time (up to 80 MHz

Clock Rate). These three enhancements allow cables 5+

meters in length to be driven.

General Description

The DS90CR481 transmitter converts 48 bits of CMOS/TTL

data into eight LVDS (Low Voltage Differential Signaling)

data streams. A phase-locked transmit clock is transmitted in

parallel with the data streams over a ninth LVDS link. Every

cycle of the transmit clock 48 bits of input data are sampled

and transmitted. The DS90CR482 receiver converts the

LVDS data streams back into 48 bits of LVCMOS/TTL data.

At a transmit clock frequency of 112MHz, 48 bits of TTL data

are transmitted at a rate of 672Mbps per LVDS data channel.

Using a 112MHz clock, the data throughput is 5.38Gbit/s

(672Mbytes/s). At a transmit clock frequency of 112MHz, 48

bits of TTL data are transmitted at a rate of 672Mbps per

LVDS data channel. Using a 66MHz clock, the data through-

put is 3.168Gbit/s (396Mbytes/s).

The chipset is an ideal means to solve EMI and cable size

problems associated with wide, high speed TTL interfaces.

The multiplexing of data lines provides a substantial cable

reduction. Long distance parallel single-ended buses typi-

cally require a ground wire per active signal (and have very

limited noise rejection capability). Thus, for a 48-bit wide

data and one clock, up to 98 conductors are required. With

this Channel Link chipset as few as 19 conductors (8 data

pairs, 1 clock pair and a minimum of one ground) are

needed. This provides an 80% reduction in cable width,

which provides a system cost savings, reduces connector

physical size and cost, and reduces shielding requirements

due to the cables’ smaller form factor.

Features

n 3.168 Gbits/sec bandwidth with 66 MHz Clock

n 5.376 Gbits/sec bandwidth with 112 MHz Clock

n 65 - 112 MHz input clock support

n LVDS SER/DES reduces cable and connector size

n Pre-emphasis reduces cable loading effects

n Optional DC balance encoding reduces ISI distortion

n Cable Deskew of +/−1 LVDS data bit time (up to 80

MHz Clock Rate)

n 5V Tolerant TxIN and control input pins

n Flow through pinout for easy PCB design

n +3.3V supply voltage

The 48 CMOS/TTL inputs can support a variety of signal

combinations. For example, 6 8-bit words or 5 9-bit (byte +

parity) and 3 controls.

n Transmitter rejects cycle-to-cycle jitter

n Conforms to ANSI/TIA/EIA-644-1995 LVDS Standard

The DS90CR481/DS90CR482 chipset is improved over prior

generations of Channel Link devices and offers higher band-

width support and longer cable drive with three areas of
