DS90CF363A Datasheet | National Semiconductor

Description The DS90C363A/DS90CF363A 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 DS90C363A transmitter can be programmed for Rising edge strobe or Falling edge strobe through a dedicated pin. The DS90CF363A is fixed as a Falling edge strobe transmitter. A Rising edge or Falling edge strobe transmitter will interoperate with a Falling edge strobe Receiver (DS90CF364) without any translation logic. This chipset is an ideal means to solve EMI and cable size problems associated with wide, high speed TTL interfaces.
