National Semiconductor has introduced a serialiser and deserialiser (serdes) chipset capable of driving high-resolution, 24-bit colour flat-panel displays with a 65MHz clock.

The two new FPD-Link II chipsets support a scalable pixel clock range (5MHz to 65MHz), for low-resolution WQVGA to XGA displays.

The fours devices are the DS90UR905Q serialiser and DS90UR906Q deserialiser, which use a low-voltage CMOS (LVCMOS) parallel interface, and the DS90UR907Q serialiser and DS90UR908Q deserialiser, which use a low-voltage differential signalling (LVDS) interface.

The DS90UR905Q and DS90UR907Q serializers embed the clock, randomize, balance, and scramble the data payload, level shift the wide parallel video bus and serialise it to a single pair.

Both serialisers operate at speeds of 140Mbit/s to 1.8Gbit/s and support 18-bits per pixel (bpp) and 24-bpp colour displays.

The DS90UR905Q and DS90UR907Q serialisers are AEC-Q100 Grade 2 qualified for operation between -40 degrees C and 105 degrees C. They also include a built-in self test (BIST) mode for factory test, system start up and diagnostics.
