Color Management System Feedback Controller

Data Sheet

Description

Features

The HDJD-J822 is a CMOS mixed-signal IC designed to

be the optical feedback controller of an LED-based light-

ing system. A typical system consists of an array of red,

green and blue LEDs, LED drivers, a tri-color photosensor

that samples the light output, and the HDJD-J822. The

IC interfaces directly to the photosensor, processes the

color information and adjusts the light output from the

LEDs until the desired color is achieved. To achieve this,

the IC integrates a high-accuracy 10-bit analog-to-digital

converter front-end, a color data processing logic core,

and a high-resolution 12-bit PWM output generator.

• –40 to 85°C operation

• I C serial interface

• Robust CMOS-Schmitt input

• CMOS/TTL compatible output

• Multiple color input formats

– CIE XYZ, Yxy, Yu’v’and RGB

• 3-channel analog interface to color sensor

– X, Y and Z channels

• 3-channel 12-bit PWM output

By employing a feedback system and the HDJD-J822,

the light output produced by the LED array maintains its

color over time and temperature. In addition, the desired

color can be speciﬁed using a standard CIE color space.

– Red, Green, and Blue LED channels

• Internal computation of calibration data

• Internal clock generator

In addition, by incorporating a standard I C serial inter-

• Internal reference voltage generator

• Error ﬂag output

face, specifying the color of the LED array’s light output

is as simple as picking the color coordinates from the

CIE color space and writing several bytes of data to the

device.

• External push-button interface

• Only passive components required externally

The output PWM signals are connected directly to the

LED drivers as enable signals. The PWM signals control

the on-time duration of the red, green and blue LEDs.

That duration is continually adjusted in real-time to

match the light output from the LED array to the speci-

ﬁed, desired color.

Applications

• Backlighting

• General illumination

• Mood/accent lighting

• Color context sensitive appliances

ESD WARNING: Standard CMOS handling precautions should be observed to avoid static discharge.
