The CS5828 receives four sets of 7-bit data in
CMOS logic level and converts them into four low-
voltage differential signaling (LVDS) serial channels.
The 7-bit input data is referenced to the CKIN signal.
The RF pin selects either rising or falling edge trigger
of CKIN. Parallel to serial conversion is performed by
a 7X internal generated clock reference using on-
chip PLL using CKIN. A copy of CKIN but phase-
locked to the output serial streams, CLKOUT, is also
converted to the fifth LVDS channel. The CS5828
offers a reliable communication media using LVDS
signaling and provides low EMI dealing with wide,
high-speed TTL interfaces.
This is especially attractive for interfaces between
GUI controller and display systems such as LCD
panels for SVGA/XGA/SXGA applications.
• Four 7-bit serial and one clock LVDS channels.
• Compatible with ANSI TIA/EIA-644 LVDS stan-
dard.
• Wide CKIN ranges from 31MHz to 85MHz.
• Fully integrated on-chip PLL that provides 7X
CKIN serial shift clock.
• Pin selectable for rising or falling edge trigger.
• Support power-down mode.
• 5V/3.3V tolerant data input.
• Single 3.3V supply operation.
• CMOS low power consumption.
• Functional compatible with DS90C385.
• Available in 56-pin TSSOP package.
