Description
Parallel Interface Data Input Pins
For 8–bit RED Display: DI7 = R7 – MSB, DI0 = R0 – LSB.
Parallel Interface Data Input Pins
For 8–bit GREEN Display: DI15 = G7 – MSB, DI8 = G0 – LSB.
Parallel Interface Data Input Pins
For 8–bit BLUE Display: DI23 = B7 – MSB, DI16 = B0 – LSB.
Control Signal Input
For Display/Video Application:
CI1 = Data Enable Input
Control signal pulse width must be 3 clocks or longer to be transmitted when the Control
Signal Filter is enabled (CONFIG[1:0] = 01). There is no restriction on the minimum
transition pulse when the Control Signal Filter is disabled (CONFIG[1:0] = 00).
The signal is limited to 2 transitions per 130 clocks regardless of the Control Signal Filter
setting.
Control Signal Input
For Display/Video Application:
CI2 = Horizontal Sync Input
Control signal pulse width must be 3 clocks or longer to be transmitted when the Control
Signal Filter is enabled (CONFIG[1:0] = 01). There is no restriction on the minimum
transition pulse when the Control Signal Filter is disabled (CONFIG[1:0] = 00).
The signal is limited to 2 transitions per 130 clocks regardless of the Control Signal Filter
setting.
Control Signal Input
For Display/Video Application:
CI3 = Vertical Sync Input
CI3 is limited to 1 transition per 130 clock cycles. Thus, the minimum pulse width allowed
is 130 clock cycle wide.
Clock Input
Latch/data strobe edge set by RFB pin.
Power-down Mode Input
PDB = 1, Ser is enabled (normal operation).
Refer to ”Power Up Requirements and PDB Pin” in the Applications Information Section.
PDB = 0, Ser is powered down
When the Ser is in the power-down state, the driver outputs (DOUT+/-) are both logic high,
the PLL is shutdown, IDD is minimized. Control Registers are RESET.
Differential Driver Output Voltage Select
VODSEL = 1, CML VOD is ±420 mV, 840 mVp-p (typ) — long cable / De-Emph applications
VODSEL = 0, CML VOD is ±280 mV, 560 mVp-p (typ) — short cable (no De-emph), low
power mode.
This is can also be control by I2C register.
De-Emphasis Control
De-Emph = open (float) - disabled
To enable De-emphasis, tie a resistor from this pin to GND or control via register.
See
This can also be controlled by I2C register access.
Clock Input Latch/Data Strobe Edge Select
RFB = 1, parallel interface data and control signals are latched on the rising clock edge.
RFB = 0, parallel interface data and control signals are latched on the falling clock edge.
This can also be controlled by I2C register access.
