DS90C383B

+3.3V 可编程 LVDS 发送器 24 位平板显示 FPD 链接 - 65 MHz

The 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 DS90C383B transmitter can be programmed for Rising edge strobe or Falling edge strobe through a dedicated pin. A Rising edge or Falling edge strobe transmitter 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.
