Applications Information
How to configure the DS90C387R to work with
DS90CF384/DS90CF384A/DS90CF386 or DS90CF388 for
most common application:
1. To configure for single pixel application using the
DS90C387R to interface with GMCH host, please see table
below for reference pin connection and configuration. Due to
the implementation differences among various GMCH ven-
dors, the table is using the GMCH vendor located in Santa
Clara, California, USA as an example. A two-wire serial
communication interface based EEPROM containing EDID
128 bytes LCD timing information may be required depend-
ing on device driver implementation.

2. To configure for single pixel application using the
DS90C387R with single DS90CF384 or DS90CF384A or
DS90CF386 LVDS based LCD panel or monitor, the “DUAL”
pin must be set to Gnd (single RGB), and “BAL” pin must be
set to Gnd to disable the feature for DS90CF384/
DS90CF386 doesn’t support DC balance function. For cable
length more than two meters, pre-emphasis feature is rec-
ommended. Please see table below for reference pin con-
nection.
3. To configure for single pixel or dual pixel application using
the DS90C387R with DS90CF388, the “DUAL” pin must be
set to Vcc (dual RGB) or Gnd (single RGB). Also, “BAL” pins
on both devices have to in the same logic state. For cable
length more than two meters, pre-emphasis feature is rec-
ommended.
4. In dual mode, DS90C387R has two LVDS clock outputs
enabling an interface to two FPD-Link ’notebook’ receivers
(DS90CF384/DS90CF386). “BAL” pin must be set to Gnd to
disable DC balance function for DS90CF384/DS90CF386
doesn’t support DC balance function. In single mode, out-
puts A4-to-A7 and CLK2 are disabled which reduces power
dissipation. For cable length more than two meters, pre-
emphasis feature is recommended.
The DS90CF388 is able to support single or dual pixel
interface up to 112MHz operating frequency. This receiver
may also be used to interface to a VGA controller with an
