Dual Voltage Video/Memory Clock Generator
Description
The ICS2496 has been specifically designed to serve the
portable PC market with operation at either 3.3V or 5V with a
comprehensive power-saving shut down mode.
The ICS2496 Clock Generator is a dual phase-locked loop
frequency synthesizer capable of generating 16 video frequen-
cies and four memory clock frequencies for use with high
performance video display systems. Utilizing CMOS technol-
ogy to implement all linear, digital and memory functions, the
ICS2496 provides a low power, small footprint, low cost
solution to the generation of video dot clocks. Provision is
made via a single level custom mask to implement customer
specific frequency sets. Phase-locked loop circuitry permits
rapid glitch-free transitions between clock frequencies.
In addition to providing 16 clock rates, the ICS2496 has
provisions to multiplex an externally-generated signal source
into the VCLK signal path. Internal phase-locked frequencies
continue to remain locked at their preset values when this mode
is selected. This feature permits instantaneous transition from
an external frequency to an internally-generated frequency.
Printed circuit board testing is simplified by the use of these
modes, as an external clock generated by the ATE tester can be
fed through, permitting synchronous testing of the entire system.
