■ Monitor Interface
Each pin of the monitor interface is used for the interface with the external monitor. Since the display data is
output in both of analog and digital signal, use them according to the specification of the external monitor
interface.
z R (Analog output
Pin No.103)
z G (Analog output
Pin No.104)
z B (Analog output
Pin No.105)
Analog RGB output pin. Analog signals: R, G, and B of the display data is output.
z IREF (Analog
Pin No.106)
A pin for the DAC reference power supply. The reference current for DAC is input.
z DR5-0 (Output PinNo.111-116)
z DG5-0 (Output PinNo.119-124)
z DB5-0 (Output PinNo.127-132)
Digital RGB output pin.
z VSYNC_N (Output
Pin No.136)
Vertical synchronizing signal output pin. The vertical synchronizing signal is output in synchronization
with DOTCLK.
z HCSYNC_N (Output
Pin No.137)
Horizontal synchronizing signal / composite synchronizing signal output pin.
The horizontal synchronizing signal or composite synchronizing signal is output in synchronization with
DOTCLK.
z VSIN_N (Input
Pin No.99)
Vertical synchronizing signal input pin.
The external vertical sync for the reset of the internal vertical counter is input.
z HSIN_N (Input
Pin No.100)
Horizontal synchronizing signal input pin. The external horizontal sync for the reset of the internal
horizontal counter is input.
z BLANK_N (Output
Pin No.138)
Display timing output pin. A signal that indicates the blank interval is output in synchronization with
DOTCLK.
z FSC (Output
Pin No.134)
Sub-carrier clock output pin. The sub-carrier clock, which is used in the video encoder is output.
z YS_N (Output
Pin No.135)
YS signal output pin. YS signal is output in synchronization with DOTCLK when superimpose is
performed.
z DOTCLK (Output
Pin No.139)
Dot clock output pin. Dot clock is output from this pin.
