MPC9608AC

Overview

The MPC9608 is a 3.3 V compatible, 1:10 PLL-based zero-delay clock buffer designed for high-performance and mid-range clock tree applications. It features a wide frequency range of 12.5 to 200 MHz with low output skews. The device includes one reference clock input and two banks of five LVCMOS outputs. A selectable divide-by-two function allows Bank B outputs to operate at half the frequency of Bank A while remaining synchronized. It supports synchronous output enable control (CLK_STOP), output tristate control, and a PLL bypass mode for low-frequency system testing.

Feature Summary

• 1:10 LVCMOS zero-delay buffer with internal PLL
• Single 3.3 V supply operation
• Clock I/O frequency range from 12.5 to 200 MHz
• Selectable divide-by-two for Bank B outputs

Applications

• Networking equipment
• Telecommunications systems
• Computer applications
• PowerQuicc I and II compatible designs

Procurement Notes

Verify that the specific ordering suffix matches the required package type and lead-free status. The AC suffix indicates a 32-lead LQFP Pb-free package. Confirm RoHS compliance requirements against the final assembly marking. Ensure the voltage domain aligns with the specified 3.3 V compatibility before procurement.

Selection Notes

Select this component when near-zero insertion delay is critical for nested clock designs. Use the F_RANGE pins to configure the operating frequency band between 12.5 MHz and 200 MHz. Utilize the BSEL pin if Bank B requires a divided clock signal. Ensure proper power supply filtering on the VCCA pin to minimize jitter and maintain phase stability.

Part Context

This part belongs to the advanced clock drivers family, specifically functioning as a PLL fanout buffer. It replaces traditional fanout buffers to achieve significantly lower clock skew. The device integrates an analog PLL circuit requiring external RC filtering on the VCCA pin to isolate digital switching noise from the sensitive analog components.
