The DS90C385AMT is a Transmitter converts 28-bits of LVCMOS/LVTTL data into four LVDS (low voltage differential signalling) data streams. A phase-locked transmit clock is transmitted in parallel with the data streams over the fifth LVDS link. Every cycle of the transmit clock 28-bits of input data are sampled and transmitted. At a transmit clock frequency of 87.5MHz, 24-bits of RGB data and 3-bits of LCD timing and control data (FPLINE, FPFRAME, DRDY) are transmitted at a rate of 612.5Mbps per LVDS data channel. Using a 87.5MHz clock, the data throughput is 306.25Mbps. This 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 FPDLink Receiver without any translation logic. This chipset is an ideal means to solve EMI and cable size problems associated with wide, high-speed TTL interfaces with added Spread Spectrum Clocking support.
● Pin-to-Pin-compatible to DS90C383, DS90C383A and DS90C385
