ICS1531Y-100 Datasheet PDF - Integrated Circuit Systems

General Description
The ICS1531 is a high-performance, cost-effective, 3-channel, 8-bit analog-to-digital converter with an integrated line-locked clock generator. It is part of a family of chips intended for high-resolution video applications that use analog inputs, such as LCD monitors, LCD projectors, plasma displays, and projection TVs. Using ICSs low-voltage CMOS mixed-signal technology, the ICS1531 is an effective data-capture solution for resolutions from VGA to UXGA.

FEATUREs
• 3-channel 8-bit analog-to-digital conversion up to 165 MHz
• Direct connection to analog input data (no external pre-amplifier circuit needed)
• Video amplifier: 500-MHz analog bandwidth, software-adjustable gain
• Dynamic Phase Adjust (DPA) for software-adjustable analog sample points
• Software selectable: One pixel per clock (for 24-bit pixels) or two pixels per clock (for a total of 48 bits)
• Internal clamp circuit. Very low jitter.
• Low-voltage TTL clock outputs, synchronized with digital pixel data outputs
• Independent software reset for PLLs and DPA
• Double-buffered PLL and DPA control registers
• Two additional PLLs with spread spectrum for memory and panel clock
• External/internal loop-filter selection with software
• Automatic Power-On Reset (POR) detection
• Uses 3.3 VDC. Digital inputs are 5-V tolerant.
• Industry-standard 2-wire serial bus interface speeds: low (100 kHz), high (400 kHz), or ultra (800 kHz)
• Lock detection available in hardware and software
• 144-pin low-profile quad flat pack (LQFP) package

APPLICATIONs
• LCD displays, LCD projectors, plasma displays, and projection TVs
