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 Setup and Hold Times on TxINPUTs
Tx power consumption < 130 mW (typ) at 65MHz Grayscale
40% Less Power Dissipation than BiCMOS Alternatives
Tx Power-down mode < 60μW (typ)
Supports VGA, SVGA, XGA and Dual Pixel SXGA.
Narrow bus reduces cable size and cost
Up to 1.8 Gbps throughput
Up to 227 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 56-lead TSSOP package
Improved replacement for:
– SN75LVDS83, DS90C383A
DESCRIPTION
The DS90C383B transmitter converts 28 bits of CMOS/TTL data into four LVDS (Low Voltage Differential Signaling) data streams. A phase-locked transmit clock is transmitted in parallel with the data streams over a fifth LVDS link. Every cycle of the transmit clock 28 bits of input data a...
