Pin Description
PIN NAME
FUNCTION
1
RED High-ESD Protection Diodes for RGB Signals
2
GRN High-ESD Protection Diodes for RGB Signals
3
BLU High-ESD Protection Diodes for RGB Signals
4
GND Ground
5
VS
Supply Voltage Output with Current-Limit Switch. VS provides a current-limited voltage from VCC when the
device is enabled. Bypass VS to GND with a 1FF or larger ceramic capacitor as close as possible to the device.
6
EN
Active-Low Enable Input. Drive EN high and EN low to disable the device. EN is weakly pulled up internally.
7
SDA0 DDC Data Input from Graphics Controller
8
SDA1 DDC Data Output to VGA Monitor. Internally pulled up to VCC.
9
SCL0 DDC Clock Input from Graphics Controller
10
SCL1 DDC Clock Output to VGA Monitor. Internally pulled up to VCC.
11 SYNCH0 Horizontal Sync Input
12 SYNCH1 Horizontal Sync Output
13 SYNCV0 Vertical Sync Input
14 SYNCV1 Vertical Sync Output
15
VCC
Supply Voltage Input. Apply a voltage between +4.75V and +5.25V to VCC to power the device. Bypass VCC
to GND with a 1FF or larger ceramic capacitor as close as possible to the device.
16
EN
Active-High Enable Input. Drive EN low and EN high to disable the device. EN is weakly pulled down internally.
Exposed Pad. Connect EP to GND. For enhanced thermal dissipation, connect EP to a large ground plane.
