MPC962308D-1H

Overview

The MPC962308D-1H is a 3.3 V zero-delay buffer designed for high-speed clock distribution in PC, workstation, datacom, and telecom applications. It utilizes an internal PLL with an external feedback path to lock the output phase to the reference clock, achieving virtually zero propagation delay. The device provides eight LVCMOS outputs with low skew characteristics: input-to-output skew is less than 250 ps, and output-to-output skew is less than 200 ps. It supports frequencies from 10 MHz to 133 MHz, operates on a single 3.3 V supply, and features two banks of four outputs with tristate control via select inputs.

Feature Summary

• Zero input-output propagation delay using internal PLL and external feedback
• Low skew performance: <250 ps input-to-output, <200 ps output-to-output
• Eight LVCMOS outputs organized in two tristatable banks of four
• Frequency range of 10 MHz to 133 MHz with cycle-cycle jitter up to 200 ps

Applications

• PC and workstation clock distribution
• Datacom and telecom systems
• High-performance application timing solutions

Procurement Notes

Verify the specific suffix 'D' indicates the 16-pin SOIC package variant when sourcing. Confirm that the '-1H' designation corresponds to the high-drive version with faster rise and fall times as specified in the configuration table. Ensure compatibility with existing PCB footprints for the 16-lead SOIC form factor.

Selection Notes

Select the MPC962308D-1H over standard variants if faster output transition times are required for signal integrity at higher frequencies. The -1H configuration maintains the same 1:8 buffering function but offers improved drive capability. Verify load capacitance requirements (15 pF for >100 MHz) to ensure operation within the specified frequency range.

Part Context

This component belongs to the MPC962308 family of zero-delay buffers originally manufactured by Motorola, now associated with Freescale Semiconductor. The family includes various configurations (-1, -2, -3, -4, -5H) offering different frequency multiplication/division options. The MPC962308D-1H specifically provides a 1:1 reference-to-output ratio with enhanced drive strength.

Replacement Considerations

The datasheet explicitly states compatibility with the CY2308 and CY23S08 devices. These can be considered as functional substitutes in designs requiring similar zero-delay buffering capabilities.
