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

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 ICS's
low-voltage CMOS mixed-signal technology, the ICS1531
is an effective data-capture solution for resolutions from
VGA to UXGA.
The ICS1531 offers analog-to-digital data conversion and
synchronized pixel clock generation at speeds of 100, 140, or
165 MHz (or mega samples per second, MSPS). The
Dynamic Phase Adjust (DPA) circuitry allows end-user
control over the pixel clock phase, relative to the recovered
sync signal and analog pixel data. Either the internal pixel
clock can be used as a capture clock input to the
analog-to-digital converters or an external clock input can be
used. The ICS1531 provides either one or two 24-bit pixels
per clock. An ADCSYNC output pin provides recovered
HSYNC from the pixel clock phase-locked-loop (PLL)
divider chain output, which can be used to synchronize
display enable output.
A clamp signal can be generated internally or provided
through the CLAMP pin. A high-bandwidth video amplifier
with adjustable gain allows fine tuning of the analog signal.
The advanced PLL uses an internal programmable feedback
divider. Two additional, independent programmable PLLs,
each with spread-spectrum functionality, support memory
