    General Description
    The
    AV9155
    is a low cost frequency generator designed spe-
    cifically for desktop and notebook PC applications. Its CPU
    clocks provide all necessary CPU frequencies for 286, 386 and
    486 systems, including support for the latest speeds of proces-
    sors. The device uses a 14.318 MHz crystal to generate the
    CPU and all peripheral clocks for integrated desktop
    motherboards.
    Features
    Compatible with 286, 386, and 486 CPUs
    Supports turbo modes
    Generates communications clock, keyboard clock,
    floppy disk clock, system reference clock, bus clock
    and CPU clock
    Output enable tristates outputs
    Up to 100 MHz at 5V or 3.3V
    20-pin DIP or SOIC
    All loop filter components internal
    Skew-controlled 2X and 1X CPU clocks
    Power-down option

    Low Cost 20-Pin Frequency Generator
    The dual 14.318 MHz clock outputs allows one output for the
    system and one to be the input to an ICS graphics frequency
    generator such as the AV9194.
    The CPU clock offers the unique feature of smooth, glitch-free
    transitions from one frequency to the next, making this ideal
    device to use whenever slowing the CPU speed. The
    AV9155
    makes a gradual transition between frequencies, so that it
    obeys the Intel cycle-to-cycle timing specification for 486
    systems. The simultaneous 2X and 1X CPU clocks offer
    controlled skew to within 1.5ns (max) of each other.
    ICS offers several versions of the
    AV9155
    . The different devices
    are shown below:
    ICS has been shipping motherboard frequency generators
    since April 1990, and is the leader in the area of multiple output
    clocks on a single chip. The
    AV9155
    is a third generation
    device, and uses ICSs patented analog CMOS phase-locked
    loop technology for low phase jitter. ICS offers a broad family
    of frequency generators for motherboards, graphics and other
    applications, including cost-effective versions with only one
    or two output clocks. Consult ICS for all of your clock
    generation needs.
