Low operating power consumption and power down capability make them ideal low-cost solutions for PC video capture applications on both desktop and portable system platforms. They support square pixel and CCIR601 resolutions for both NTSC and PAL. They have a flexible pixel port which supports a variety of system interface configurations, and they are offered in both a 100-pin PQFP and 100-pin TQFP.
