概要
Description
ICS9112AM-16 is a dual-output, programmable clock generator (PLL-based) from Integrated Circuit Systems (ICS). It takes a reference clock (crystal or oscillator) and synthesizes two low-jitter system clocks with programmable frequencies. The AM-16 denotes the package/revision (a 16-pin device). Programming is via a serial control interface (I2C-like) to set frequencies, divider/multiplier ratios, and output formats. Features typically include selectable output formats, variable drive strength, optional spread-spectrum modulation, power-down, and a power-on reset. Applications: CPUs, FPGAs, memory, and other digital systems requiring multiple synchronized clocks from a single reference. For exact specs—frequencies, jitter, voltage, and interface details—consult the latest ICS9112AM-16 datasheet from the manufacturer.
Equivalent
ICS9112AM-16 is a multi-output clock generator/distributor. There is no single universal direct replacement; equivalents depend on required specs (input freq, output count/types, voltage, jitter, package). Common functional matches include TI CDCE913 (4-output clock distributor), TI CDCLVC110/120 (low-skew buffers), IDT 6T49N/9N series, and Renesas ISL-series clock buffers. For an exact match, provide target specs or use a distributor cross-reference tool.
