Product Summary
The ICS9169CM-23LF is a low-cost frequency generator designed specifically for Pentium-based chip set systems. The integrated buffer minimizes skew and provides all the clocks required. A 14.318 MHz crystal provides the reference clock to generate standard Pentium frequencies. The ICS9169CM-23LF CPU clock makes gradual frequency transitions without violating the PLL timing of internal microprocessor clock multipliers.
Parametrics
ICS9169CM-23LF absolute maximum ratings: (1)Supply Voltage: 7.0 V; (2)Logic Inputs: GND –0.5 V to VDD +0.5 V; (3)Ambient Operating Temperature: 0 to +70℃; (4)Storage Temperature: –65 to +150℃.
Features
ICS9169CM-23LF features: (1)Eight selectable CPU clocks operate up to 83.3 MHz; (2)Maximum CPU jitter of ±200ps; (3)Six BUS clocks support sync or async bus operation; (4)250ps skew window for CPU outputs, 500ps skew window for BUS outputs; (5)CPU clocks to BUS clocks skew 1-4 ns (CPU early); (6)48 MHz clock for USB support & 24 MHz clock for FD.; (7)Logic inputs latched at Power-On for frequency selection saving pins as Input/Output; (8)Integrated buffer outputs drive up to 30pF loads; (9)3.0V - 3.7V supply range, CPU (1:6) outputs 2.5V (2.375 - 2.6V) VDD option; (10)28-pin SOIC package.
