DS90CR483 / DS90CR484  
48-Bit LVDS Channel Link SER/DES — 33 - 112 MHz  
pre-emphasis feature that provides additional output current  
General Description  
during transitions to counteract cable loading effects. Op-  
The DS90CR483 transmitter converts 48 bits of CMOS/TTL  
tional DC balancing on a cycle-to-cycle basis, is also pro-  
data into eight LVDS (Low Voltage Differential Signaling)  
vided to reduce ISI (Inter-Symbol Interference). With pre-  
data streams. A phase-locked transmit clock is transmitted in  
emphasis and DC balancing, a low distortion eye-pattern is  
parallel with the data streams over a ninth LVDS link. Every  
provided at the receiver end of the cable. A cable deskew  
cycle of the transmit clock 48 bits of input data are sampled  
capability has been added to deskew long cables of pair-to-  
and transmitted. The DS90CR484 receiver converts the  
pair skew of up to +/−1 LVDS data bit time (up to 80 MHz  
LVDS data streams back into 48 bits of CMOS/TTL data. At  
Clock Rate). These three enhancements allow cables 5+

are transmitted at a rate of 672Mbps per LVDS data channel.  
The chipset is an ideal means to solve EMI and cable size  
Using a 112MHz clock, the data throughput is 5.38Gbit/s  
problems associated with wide, high speed TTL interfaces.  
(672Mbytes/s).  
For more details, please refer to the “Applications Informa-  
tion” section of this datasheet.  
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  
Features  
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.  
n Up to 5.38 Gbits/sec bandwidth  
n 33 MHz to 112 MHz input clock support  
n LVDS SER/DES reduces cable and connector size  
n Pre-emphasis reduces cable loading effects  
n DC balance data transmission provided by transmitter  
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.  
The DS90CR483/DS90CR484 chipset is improved over prior  
generations of Channel Link devices and offers higher band-  
width support and longer cable drive with three areas of  
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  
n Transmitter rejects cycle-to-cycle jitter  
n Conforms to ANSI/TIA/EIA-644-1995 LVDS Standard  
n Both devices are available in 100 lead TQFP package
