PCK2001MDB,112

Clock Buffers, Drivers Overview

The PCK2001MDB,112 is a mobile version of the PCK2001, functioning as a 1-to-10 fanout clock buffer. It supports frequencies from 14.318 MHz to 150 MHz and operates on a single 3.3 V supply. The device features an I2C serial interface for individual output enable/disable control. Key electrical parameters include a typical propagation delay of 2.5 ns, rise time of 1.0 ns, fall time of 700 ps, and total supply current of 50 μA at 3.465 V. It provides 175 ps skew between outputs and is housed in a 28-pin SSOP package.

Clock Buffers, Drivers Feature Summary

• 1-to-10 fanout buffer optimized for 66 MHz, 100 MHz, and 133 MHz operation
• Individual clock output enable/disable via I2C serial interface
• Typically used to support two SDRAM DIMMs in laptop or mobile applications
• 175 ps skew outputs with 2.5 ns typical propagation delay

Clock Buffers, Drivers Applications

• SDRAM clock distribution for up to 2 SDRAM DIMMs
• 133/100 MHz CPU clock distribution
• 66/33 MHz PCI clock distribution
• 14.318 MHz reference clock distribution

Clock Buffers, Drivers Procurement Notes

Verify that the component matches the Philips Semiconductors product specification dated May 17, 2000. Confirm the 28-pin SSOP package (SOT341-1) and the specific ordering code PCK2001M DB. Ensure the operating temperature range aligns with the 0°C to +70°C requirement specified in the documentation.

Clock Buffers, Drivers Selection Notes

Select this component when a reduced pincount solution is required compared to the 48-pin PCK2001. It is suitable for designs needing up to 10 buffered outputs for SDRAM or system clocks. Ensure the design accommodates the 3.3 V supply voltage and utilizes the I2C interface for dynamic output control if needed.

Clock Buffers, Drivers Part Context

This part is a mobile variant of the PCK2001, designed specifically for space-constrained applications like laptops. While the standard PCK2001 offers 18 outputs in a 48-pin package, the PCK2001M reduces this to 10 outputs in a 28-pin SSOP package, maintaining identical functional characteristics and performance metrics.

Clock Buffers, Drivers Replacement Considerations

The PCK2001 serves as the primary reference part. It shares the same general features but differs in pin count and package size (48-pin vs. 28-pin). Verify that the application requires only 10 outputs; otherwise, the PCK2001 may be necessary to support up to 4 SDRAM DIMMs.
