FEATURES
1
2 Up to 105 Megabyte/sec bandwidth
• Narrow bus reduces cable size and cost
• 290 mV swing LVDS devices for low EMI
• Low power CMOS design
• Power-down mode
• PLL requires no external components
• Low profile 48-lead TSSOP package
• Rising edge data strobe
• Compatible with TIA/EIA-644 LVDS standard
DESCRIPTION
The DS90CR561 transmitter converts 21 bits of
CMOS/TTL data into three LVDS (Low Voltage
Differential Signaling) data streams. A phase-locked
transmit clock is transmitted in parallel with the data
streams over a fourth LVDS link. Every cycle of the
transmit clock 21 bits of input data are sampled and
transmitted. The DS90CR562 receiver converts the
LVDS data streams back into 21 bits of CMOS/TTL
data. At a transmit clock frequency of 40 MHz, 18 bits
of RGB data and 3 bits of LCD timing and control
data (FPLINE, FPFRAME, DRDY) are transmitted at
a rate of 280 Mbps per LVDS data channel. Using a
40 MHz clock, the data throughput is 105 Megabytes
per second. These devices are offered with rising
edge data strobes for convenient interface with a
variety of graphics and LCD panel controllers.
This chipset is an ideal means to solve EMI and
cable size problems associated with wide, high speed
TTL interfaces.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
