PCK2002PLPW,118

Clock Buffers, Drivers Overview

The PCK2002PL is a 1-to-4 fanout clock buffer designed for general-purpose and PCI-X applications, operating at frequencies up to 533 MHz. It distributes one buffered input clock signal to four output clocks with low skew characteristics. The device operates on a 3.3 V supply and features part-to-part skew of less than 500 ps and low output skew under 200 ps. It is housed in an 8-pin TSSOP package (3.1 x 4.4 mm) and offers ESD protection exceeding 2000 V HBM.

Clock Buffers, Drivers Feature Summary

• 1:4 fanout buffer supporting 0–533 MHz operation
• Low output skew (<200 ps) and part-to-part skew (<500 ps)
• Compatible form, fit, and function with CDCV304
• 8-pin TSSOP package with 3.3 V operation

Clock Buffers, Drivers Applications

• PCI-X clock distribution
• General-purpose clock buffering
• High-performance system clocking

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering code PCK2002PLPW for the 8-pin TSSOP variant. Confirm temperature range requirements (-40 to +85 °C) against application needs. Check for superseded documentation versions as the data sheet has undergone revisions. Ensure compatibility with existing PCB footprints referencing the SOT530-1 drawing number.

Clock Buffers, Drivers Selection Notes

Select this component when a single clock source must drive four loads with minimal skew. Compare against similar buffers like the CDCV304 for direct replacement scenarios. Consider the 3.3 V logic level compatibility with downstream devices. Evaluate capacitive load limits (20–30 pF) to ensure signal integrity at target frequencies.

Clock Buffers, Drivers Part Context

This device belongs to the Philips Semiconductors (now NXP) PCK200x series of clock buffers. Related parts include the PCK2001P (TSSOP-8), PCK2001/2 (48-pin), PCK2001M/2M (28-pin), and PCK2001R (16-pin). These components share similar low-skew technologies but vary in fanout ratios and package sizes.

Clock Buffers, Drivers Replacement Considerations

The PCK2002PL is pin-compatible with the CDCV304. Designers can use it as a drop-in replacement where form, fit, and function alignment is required. Verify that the replacement meets the specific skew and frequency requirements of the original design.
