General Description
Pentium is a trademark of Intel Corporation Low-Cost 16-Pin Frequency Generator AV9154A . The AV9154A is a 0.8mm version of the industry leading AV9154. Like the AV9154, the AV9154A is a low-cost frequency generator designed for general purpose PC and disk drive applications. However, because the AV9154A uses 0.8mm technology and the latest phaselocked loop architecture, it offers performance advantages that enable the device to be sold into Pentium™ systems.

FEATUREs
• Compatible with 386, 486 and Pentium CPUs
• 45/55 Duty cycle
• Runs up to 66 MHz at 3.3V
• Single pin can slow clock to 8 MHz (on -42 and -43)
• Single pin can stop the CPU clock glitch-free (on -43)
• Very low jitter, ±250ps for Pentium frequencies
• 1X and 2X CPU clocks skew controlled to ±250ps (-42
   only)
• Smooth transitions between all CPU frequencies
• Slow frequency ramp at power-on avoids CPU lock-up
• 16-pin PDIP or 150-mil skinny SOIC packages
• 0.8µm CMOS technology

APPLICATIONs
   Computer motherboards: The AV9154A-ST replaces crystals
   and oscillators, saving board space, component cost, part
   count and inventory costs. It produces a switchable CPU clock
   and up to four fixed clocks to drive floppy disk, communications,
   super I/O, Bus, and/or keyboard devices. The small package
   and 3.3V operation is perfect for handheld computers.
