The DS90C385 transmitter converts 28 bits of LVCMOS/LVTTL 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 85 MHz, 24 
bits of RGB data and 3 bits of LCD timing and control data (FPLINE, FPFRAME, DRDY) 
are transmitted at a rate of 595 Mbps per LVDS data channel. Using a 85 MHz clock, the 
data throughput is 297.5 Mbytes/sec. Also available is the DS90C365 that converts 21 bits 
of LVCMOS/LVTTL data into three LVDS (Low Voltage Differential Signaling) data streams. 
Both transmitters 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 (DS90CF386/DS90CF366) without any translation logic. 

The IT8888F is a PCI to ISA bridge single function device. The IT8888F serves as a bridge 
between the PCI bus and ISA bus. The IT8888F’s 32-bit PCI bus interface is compliant with 
PCI Specification V2.1 and supports both PCI Bus Master & Slave.
