PCK3807AD,112

Clock Buffers, Drivers Overview

The PCK3807AD,112 is a 1:10 Low Voltage Transistor-Transistor Logic (LVTTL) clock distribution device manufactured by NXP USA Inc. It provides low skew clock driver capabilities with a single input and ten outputs to reduce loading on preceding drivers. The component operates from a single 2.5 V or 3.3 V supply voltage within the industrial temperature range of –40 °C to +85 °C. Key electrical parameters include an input capacitance of 2.5 pF typical, output rise/fall times of 1.0 ns, and propagation delays ranging from 1.3 ns to 4.5 ns depending on load conditions. It supports operation up to 150 MHz.

Clock Buffers, Drivers Feature Summary

• 1:10 fan-out LVTTL clock distribution with low output skew
• Operates on single 2.5 V or 3.3 V supply
• Low capacitance inputs with hysteresis for improved noise margins
• Multiple power and ground pins to reduce noise

Clock Buffers, Drivers Applications

• Clock and signal distribution networks
• High-speed digital systems requiring precise timing
• Industrial equipment operating in wide temperature ranges

Clock Buffers, Drivers Procurement Notes

Verify the ordering code PCK3807AD corresponds to the 20-Pin Plastic SO package (SOT163-1). Confirm the suffix ,112 matches the specific tape-and-reel quantity or variant requirements specified by the manufacturer. Ensure compatibility with the -40 °C to +85 °C industrial temperature rating for your application environment.

Clock Buffers, Drivers Selection Notes

Select this device when a single clock source needs to drive ten loads with minimal skew. Ensure the system voltage aligns with the 2.3 V to 3.6 V operating range. Consider the 50 pF maximum output capacitance load capability when designing trace lengths and termination strategies for frequencies up to 150 MHz.

Clock Buffers, Drivers Part Context

This component belongs to the Philips/NXP Semiconductors integrated circuit portfolio, specifically designed as a clock buffer. It supersedes earlier data sheets from June 2003. The 'AD' designation indicates the 20-pin Small Outline (SO) plastic package variant.

Clock Buffers, Drivers Replacement Considerations

Check for direct pin-compatible alternatives from NXP or other manufacturers offering 1:10 LVTTL clock buffers. Verify that replacement parts meet the same 150 MHz frequency and low skew specifications.
