HV7121B
CMOS IMAGE SENSOR
With 8-bit ADC
Electronics Industries Co., Ltd. System IC Division
DESCRIPTION
HV7121B is a highly integrated single chip CMOS color image sensor using Hyundai 0.5um CMOS process developed for image application to realize high efficiency R/G/B photo sensor. The sensor has 414X314 pixels total, and 400X300 pixels effective. Each pixel is high photo sensitive, small size active pixel element that converts photons to analog voltage signal. The sensor has three on-chip 8 bit Digital to Analog Convert (DAC) and 414 comparators to digitize the pixel output. The three on-chip 8 bit DAC can be used for independent R/G/B gain control. Hyundai proprietary on-chip CDS circuit can reduce Fixed Pattern Noise (FPN) dramatically. The whole 8 bit digital color raw data is directly available on the package pins and just few control signals are needed for whole chip control, so it is very ease to configure a system using the sensor.

MCLK

INPUT / OUTPUT AC CHARACTERISTICS
l All output timing delays are measured with output load 60[pF]. l Output delay include the internal clock path delay[6ns] and output driving delay that changes in
respect to the output load, the operating environment, and a board design.
l Due to the variable valid time delay of the output, output signals may be latched in the negative
edge of MCLK for the stable data transfer between the image sensor and a host for less than 15MHz operation.
