Check for Samples: DS90C363B
FEATURES
1
23 No special start-up sequence required
between clock/data and /PD pins. Input signal
(clock and data) can be applied either before
or after the device is powered.
• Support Spread Spectrum Clocking up to
100kHz frequency modulation and deviations
of ±2.5% center spread or 5% down spread.
• "Input Clock Detection" feature will pull all
LVDS pairs to logic low when input clock is
missing and when /PD pin is logic high.
• 18 to 68 MHz shift clock support
• Best–in–Class Set & Hold Times on TxINPUTs
• Tx power consumption < 130 mW (typ) at
65MHz Grayscale
• 40% Less Power Dissipation than BiCMOS
Alternatives
• Tx Power-down mode < 37μW (typ)
• Supports VGA, SVGA, XGA and Dual Pixel
SXGA.
• Narrow bus reduces cable size and cost
• Up to 1.3 Gbps throughput
• Up to 170 Megabytes/sec bandwidth
• 345 mV (typ) swing LVDS devices for low EMI
• PLL requires no external components
• Compatible with TIA/EIA-644 LVDS standard
• Low profile 48-lead TSSOP package
• Improved replacement for:
– SN75LVDS84, DS90C363A
DESCRIPTION
The DS90C363B 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. At a transmit clock frequency of 65 MHz,
18 bits of RGB data and 3 bits of LCD timing and
control data (FPLINE, FPFRAME, DRDY) are
transmitted at a rate of 455 Mbps per LVDS data
channel. Using a 65 MHz clock, the data throughput
is 170 Mbytes/sec. The DS90C363B transmitter can
be programmed for Rising edge strobe or Falling
edge strobe through a dedicated pin. A Rising edge
or Falling edge strobe transmitter will interoperate
with a Falling edge strobe Receiver (DS90CF366)
without any translation logic.
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.
