DS90C383B www.ti.com SNLS177G – APRIL 2004 – REVISED APRIL 2013 Programmable LVDS Transmitter 24-Bit Flat Panel Display (FPD) Link-65 MHz Check for Samples: DS90C383B 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...
