FUNCTION
Ground
Video Input 2. Chroma Channel.
Charge Pump A Ground
Charge Pump A Power Supply. Bypass with a 0.1µF capacitor to GND_CPA.
Positive Power Supply. Bypass to GND with a 0.1µF capacitor.
Channel 3 and Channel 4 Enable. Connect to V_S to enable channels. ENABLE_A must be tied to
ENABLE_B.
Video Input 3. Luma Channel.
Video Input 4. Chroma Channel.
No Connect.
Charge Pump B Ground.
Charge Pump B Power Supply. Bypass with a 0.1µF capacitor to GND_CPB.
Charge-Pump B Flying Capacitor Negative Terminal. Connect a 0.1µF capacitor from CAPB+ to
CAPB-.
Charge-Pump B Flying Capacitor Positive Terminal. Connect a 0.1µF capacitor from CAPB+ to CAPB-
.
Charge Pump Negative Output. Bypass with a 0.22µF capacitor to GCP2.
Negative Supply for Channels 3 and 4. Connect an RC filter between VEEB_IN and VEEB_OUT. See
Typical Application Diagram. VEEA_IN must be tied to VEEB_IN.
Video Output 4
Video Output 3
Sync Input. Sync logic input for Channel 4.
Sync Output. Sync logic output from Channel 3.
Channel 3 and Channel 4 Charge Pump Clock Output. Can also be driven by external clock. CLK_A
must be tied to CLK_B.
Charge-Pump A Flying Capacitor Negative Terminal. Connect a 0.1µF capacitor from CAPA+ to
CAPA-.
Charge-Pump A Flying Capacitor Positive Terminal. Connect a 0.1µF capacitor from CAPB+ to
CAPB-.
Charge Pump Negative Output. Bypass with a 0.22µF capacitor to GND_CPA.
Negative Supply for Channels 1 and 2. Connect an RC filter between VEEA_IN and VEEA_OUT. See
Typical Application Diagram. VEEA_IN must be tied to VEEB_IN.
Video Output 2
Video Output 1
Sync Input. Sync logic input for Channel 2.
Sync Output. Sync logic output from Channel 1.
Channel 1 and Channel 2 Charge Pump Clock Output. Can also be driven by external clock. CLK_A
must be tied to CLK_B.
Channel 1 and Channel 2 enable. Connect to V_S to enable channels. ENABLE_A must be tied to
ENABLE_B.
