Z9974

3.3V, 125-MHz, Multi-Output Zero Delay Buffer

The Z9974 integrates PLL technology for zero delay propaga-

tion from input to output. The PLL feedback is externally avail-

Features

• Output Frequency up to 125 MHz

• Supports PowerPC^®, and Pentium^®processors

• 15 Clock outputs: frequency configurable

• Two Reference clock inputs for dynamic toggling

• Output Three-State control

• Spread spectrum compatible

• 3.3V power supply

• Pin compatible with MPC974

• Industrial temperature range: –40°C to +85°C

• 52-pin TQFP package

able for propagation delay tuning and divide ratio alternatives

as per Table 1.

The Z9974 has three banks of outputs with independent divid-

er stages. These dividers allow the banks to have different

frequencies as per Table 2.

TCLK0 and TCLK1 are selectable input reference clocks and

may be toggled dynamically during operation to provide mod-

ulation and phase shifting designs.

This device includes a Master Reset signal, which disables the

outputs (Hi-Z) mode, and reset all internal digital circuitry (ex-

cluding the PLL).

An Output Enable, OE, input pin is available for disabling the

Qa(0:4), Qb(0:4), and Qc(0:3) outputs and forcing them to

LOW state. All outputs are held LOW with input clock turned

off.

Description

The Z9974 is a low-cost 3.3V zero delay clock driver for

high-speed signal buffering and redistribution.

The designer can select various Input/Output Frequency by

setting fsela, fselb, fselc, fselFB(0:1), and VCO_Sel.
