The DS90C363BMTX/NOPB is a programmable LVDS Transmitter converts 21 bits of CMOS/TTL data into three LVDS (Low Voltage Differential Signalling) 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 65MHz, 18 bits of RGB data and 3 bits of LCD timing and control data (FPLINE, FPFRAME, DRDY) are transmitted at a rate of 455Mbps per LVDS data channel. Using a 65MHz clock, the data throughput is 170Mbps. The DS90C363B 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 (DS90CF366) without any translation logic. This chipset is an ideal means to solve EMI and cable size problems associated with wide and high speed TTL interfaces.
No special start-up sequence required between clock/data and /PD pins
