MPC9608FA

Overview

The MPC9608 is a 3.3 V compatible, 1:10 PLL-based zero-delay clock buffer manufactured by Freescale Semiconductor (NXP). It features a single reference clock input and two banks of five LVCMOS outputs. The device supports an I/O frequency range of 12.5 to 200 MHz with selectable divide-by-two for one output bank. It operates on a single 3.3 V supply within an ambient temperature range of -40 °C to +85 °C. Packaged in a 7x7 mm² 32-lead LQFP, it provides low output skew and synchronous enable control.

Feature Summary

• 1:10 LVCMOS zero-delay buffer with internal PLL
• Supports clock frequencies from 12.5 MHz to 200 MHz
• Selectable divide-by-two for Bank B outputs
• Synchronous output enable (CLK_STOP) and high-impedance tristate control

Applications

• Networking equipment
• Telecommunications systems
• Computer applications
• PowerQuicc I and II microprocessor platforms

Procurement Notes

Verify the ordering suffix against the package type. The 'FA' suffix indicates a standard 32-lead LQFP package, while the 'AC' suffix denotes a lead-free version of the same 32-lead LQFP package. Confirm the specific suffix requirement matches the intended manufacturing process before procurement.

Selection Notes

Select this component for nested clock tree designs requiring near-zero insertion delay. Ensure the system requires a 3.3 V supply and LVCMOS compatibility. Verify that the required frequency falls within the 12.5–200 MHz range defined by the F_RANGE pins. Consider the separate VCCA power supply filtering requirements for optimal jitter performance.

Part Context

This device belongs to the Advanced Clock Drivers family from Freescale Semiconductor. It is designed as a fanout buffer to replace traditional CMOS buffers, offering significantly lower clock skew through its PLL-based zero-delay architecture. It targets mid-range clock distribution in high-performance digital systems.
