3 / 17 page ISL59911 3 FN7548.0 September 2, 2011 Pin Descriptions PIN NUMBER PIN NAME PIN FUNCTION 1 ADDR1 Digital Input. I2C Address select bit 1, used with ADDR0 to select the ISL59911 I2C address (see “ISL59911 Serial Communication” on page 13). Note: If power supply sequencing cannot be guaranteed, ADDR1 must be held low during power-up. See “Power Supply Sequencing” on page 10 for more information. 2V-D Power Supply Pin. -5V for internal digital logic (internal logic operates between GND and V-D). Connect to the same -5V supply as V-. 3 V- Power Supply Pin. -5V supply for analog core of chip, also tied to thermal pad. Connect to a -5V supply. 4RIN+ Analog Input. Red positive differential input 5RIN- Analog Input. Red negative differential input 6GIN+ Analog Input. Green positive differential input 7GIN- Analog Input. Green negative differential input 8BIN+ Analog Input. Blue positive differential input 9BIN- Analog Input. Blue negative differential input 10 V+ Power Supply Pin. +5V supply for analog core of chip. Connect to a +5V supply. 11 HSOUT/RCM Output configuration (Note 4) = 0: Digital Output. Decoded Horizontal Sync signal Output configuration (Note 4) = 1: Analog Output. Red common-mode voltage at inputs 12 VSOUT/GCM Output configuration (Note 4) = 0: Digital Output. Decoded Vertical Sync signal Output configuration (Note 4) = 1: Analog Output. Green common-mode voltage at inputs 13 BCM Output configuration (Note 4) = 0: Digital Output. Logic low Output configuration (Note 4) = 1: Analog Output. Blue common-mode voltage at inputs 14 ENABLE Digital Input. Chip enable logic signal. 0V: All analog circuitry turned off to reduce current. 5V: Normal operation. 15 GND Power Supply Pin. Ground reference for ISL59911. This pin must be tied to GND. 16 BREF Analog Input. Blue channel analog offset reference voltage. Typically tied to GND. 17 V-B Power Supply Pin. -5V supply for blue output buffer. Connect to the same -5V supply as V-. 18 BOUT Analog Output. Blue output voltage referenced to BREF pin. 19 V+B Power Supply Pin. +5V supply for blue output buffer. Connect to the same +5V supply as V+. 20 V+G Power Supply Pin. +5V supply for green output buffer. Connect to the same +5V supply as V+. 21 GOUT Analog Output. Green output voltage referenced to GREF pin. 22 V-G Power Supply Pin. -5V supply for green output buffer. Connect to the same -5V supply as V-. 23 V-R Power Supply Pin. -5V supply for red output buffer. Connect to the same -5V supply as V-. 24 ROUT Analog Output. Red output voltage referenced to RREF pin. 25 V+R Power Supply Pin. +5V supply for red output buffer. Connect to the same +5V supply as V+. 26 GND Power Supply Pin. Ground reference for ISL59911. 27 GREF Analog Input. Green channel analog offset reference voltage. Typically tied to GND. 28 RREF Analog Input. Red channel analog offset reference voltage. Typically tied to GND. 29 GND Power Supply Pin. Ground reference for ISL59911. This pin must be tied to GND. 30 SCL Digital Input. I2C Clock Input 31 SDA Digital Input/Open-Drain Digital Output. I2C Data Input/Output 32 ADDR0 Digital Input. I2C Address select bit 0, used with ADDR1 to select the ISL59911 I2C address. Thermal Pad Thermal Pad Power Supply Pin. Connect to -5V supply plane with multiple vias to reduce thermal resistance and more effectively spread heat from the ISL59911 to the PCB. NOTE: 4. Output Configuration is controlled via Configuration Register 0x01, bit 0. |
