Description: The DS90CF383B transmitter converts 28 bits of CMOS/TTL data into four LVDS (Low Voltage Differential ...
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
`BestinClass Set & Hold Times on TxINPUTs
`Tx power consumption < 130 mW (typ) @65MHz Grayscale
`40% Less Power Dissipation than BiCMOS Alternatives
`Tx Power-down mode < 60W (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, DS90CF383A
