The DS90CF383B is a programmable LVDS transmitter that converts 28 bits of CMOS/TTL data into four LVDS data streams. It supports a transmit clock frequency of 65 MHz and can transmit 24 bits of RGB data and 3 bits of LCD timing and control data at a rate of 455 Mbps per LVDS data channel. 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.
The DS90CF383B is a +3.3V Programmable LVDS Transmitter designed to convert 28 bits of CMOS/TTL data into four LVDS data streams and one transmit clock stream. It supports up to 65 MHz shift clocks, enabling data throughput of up to 227 Mbytes/sec for applications such as VGA, SVGA, XGA, and SXGA displays.
