The DS90C363B is a 3.3V programmable LVDS transmitter that converts 21 bits of CMOS/TTL data into three LVDS data streams. It supports a transmit clock frequency of 65 MHz, with a transmission rate of 455 Mbps per LVDS data channel, resulting in a data throughput of 170 Mbytes/sec. The transmitter can be programmed for rising edge or falling edge strobe mode through a dedicated pin. This product is ideal for solving EMI and cable size issues associated with wide, high-speed TTL interfaces.
The DS90C363B is a +3.3V programmable Low Voltage Differential Signaling (LVDS) transmitter designed for 18-Bit Flat Panel Display (FPD) Links with frequencies up to 65 MHz. It converts 21 bits of CMOS/TTL data into three LVDS data streams and transmits a phase-locked clock in parallel over a fourth link.
Key features include support for Spread Spectrum Clocking, an Input Clock Detection feature that pulls LVDS pairs low when the clock is missing, and compatibility with both rising and falling edge strobe receivers. The device supports VGA, SVGA, XGA, and Dual Pixel SXGA resolutions.
