28:4 LVDS Transmitter
CS5824
GENERAL DESCRIPTION
The CS5824 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 CS5824
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.
