PCK351DB,112

Clock Buffers, Drivers Overview

The PCK351DB,112 is a high-performance 3.3 V LVTTL clock distribution device featuring one input and ten outputs with three-state capability. It distributes a single clock signal with minimal output and pulse skew. The component operates within a supply voltage range of 3.0 V to 3.6 V and supports an industrial temperature range of −40 °C to +85 °C. Key electrical parameters include propagation delays of 3.1 ns to 4.1 ns at 3.3 V, balanced drive strengths of ±32 mA, and low output capacitance of 6 pF. The DB suffix indicates the SSOP24 plastic shrink small-outline package.

Clock Buffers, Drivers Feature Summary

• 1:10 LVTTL clock distribution with three-state outputs
• Low output-to-output skew (max 0.5 ns) and pulse skew (max 0.8 ns)
• Balanced high-drive outputs providing -32 mA IOH and 32 mA IOL
• Overvoltage tolerant inputs and outputs compatible with LVTTL levels

Clock Buffers, Drivers Applications

• Clock distribution in digital systems requiring low skew
• High-speed data transmission interfaces
• Telecommunications equipment timing circuits

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix '112' against current manufacturer documentation, as the provided datasheet lists only 'PCK351DB'. Confirm the active product status and availability through official NXP channels, as older Philips Semiconductors products may have lifecycle changes not reflected in legacy data sheets.

Clock Buffers, Drivers Selection Notes

Select this component for applications requiring precise clock synchronization across multiple loads. Ensure the design accommodates the 3.0 V to 3.6 V supply range and utilizes the distributed VCC and GND pins to minimize switching noise. Verify that the load capacitance per output does not exceed specifications to maintain the stated propagation delay and skew performance.

Clock Buffers, Drivers Part Context

The PCK351 series includes variants such as PCK351D (SO24) and PCK351DB (SSOP24). The PCK351DB,112 specifically refers to the shrink small-outline package version. This device belongs to the family of high-performance clock drivers designed for LVTTL logic families, emphasizing low power dissipation via QUBiC-LP process technology.

Clock Buffers, Drivers Replacement Considerations

Direct replacement requires matching the 1:10 LVTTL distribution function, 3.3 V operation, and SSOP24 package. Verify pin compatibility and electrical characteristics, particularly propagation delay and drive strength, against the original design requirements.
