The DS90CF383B 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 are sampled and transmitted. At a transmit clock frequency of 65 MHz, 24 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 227 Mbytes/sec. The DS90CF383B is fixed as a Falling edge strobe transmitter and will interoperate with a Falling edge strobe Receiver (DS90CF386) without any translation logic.

This chipset is an ideal means to solve EMI and cable size problems associated with wide, high speed TTL interfaces.

  • 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 & 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) @65MHz Grayscale
  • 40% Less Power Dissipation Than BiCMOS Alternatives
  • Tx Power-down Mode < 60μW (typ)
  • Supports VGA, SVGA, XGA and Dual Pixel SXGA.
  • Narrow Cus 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, DS90CF383A
