DS90CF383 DS90CF383 +3.3V LVDS Transmitter 24-Bit Flat Panel Display (FPD) Link-65 MHz Literature Number: SNLS005 DS90CF383 +3.3V LVDS Transmitter 24-Bit Flat Panel Display (FPD) Link— 65 MHz General Description Features The DS90CF383 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 throughputs is 227 Mbytes/sec. This chipset is an ideal means to solve EMI and cable size problems associated with wide, high speed TTL interfaces. n n n n n n n n n n n n n n n n 20 to 65 MHz shift clock support Single 3.3V supply Chipset (Tx + Rx) power consumption < 250 mW (typ) Power-down mode ( < 0.5 mW total) Single pixel per clock XGA (1024x768) ready Supports VGA, SVGA, XGA and higher addressability.

Applications Information and receiver devices. This change may enable the removal of a 5V supply from the system, and power may be supplied from an existing 3V power source. The DS90CF383 and DS90CF384 are backward compatible with the existing 5V FPD Link transmitter/receiver pair (DS90CF583 and DS90CF584). To upgrade from a 5V to a 3.3V system the following must be addressed: 1. Change 5V power supply to 3.3V. Provide this supply to the VCC, LVDS VCC and PLL VCC of both the transmitter 2. The DS90CF383 transmitter input and control inputs accept 3.3V TTL/CMOS levels. They are not 5V tolerant.
