DS90C387, DS90CF388
www.ti.com SNLS012H – MAY 2000 – REVISED APRIL 2013 DS90C387, DS90CF388 Dual Pixel LVDS Display Interface (LDI)-SVGA/QXGA
Check for Samples: DS90C387, DS90CF388 FEATURES DESCRIPTION The DS90C387/DS90CF388 transmitter/receiver pair
is designed to support dual pixel data transmission
between Host and Flat Panel Display up to QXGA
resolutions. The transmitter converts 48 bits (Dual
Pixel 24-bit color) of CMOS/TTL data into 8 LVDS
(Low Voltage Differential Signalling) data streams.
Control signals (VSYNC, HSYNC, DE and two userdefined signals) are sent during blanking intervals. At
a maximum dual pixel rate of 112MHz, LVDS data
line speed is 672Mbps, providing a total throughput of
5.38Gbps (672 Megabytes per second). Two other
modes are also supported. 24-bit color data (single
pixel) can be clocked into the transmitter at a
maximum rate of 170MHz. In this mode, the
transmitter provides single-to-dual pixel conversion,
and the output LVDS clock rate is 85MHz maximum.
The third mode provides inter-operability with FPDLink devices. 1 2 Complies with OpenLDI Specification for
Digital Display Interfaces
