PI6C182BHE

Clock Buffers, Drivers Overview

The PI6C182BHE is a precision 1-to-10 non-inverting clock buffer designed for SDRAM applications, supporting frequencies up to 140 MHz. It operates on a single 3.3V supply and features low skew of less than 250 ps between outputs. The device includes an I2C serial interface for individual output enable/disable control and utilizes multiple VDD/VSS pins to minimize noise. It is housed in a 28-pin SSOP package and supports an industrial temperature range from -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Precision 1-to-10 non-inverting buffer with low skew (<250 ps)
• Supports SDRAM clock frequencies up to 140 MHz
• I2C serial configuration for individual output activation/deactivation
• Multiple power and ground pins for noise reduction

Clock Buffers, Drivers Applications

• SDRAM clock distribution for memory modules
• Buffering clocks for up to four SDRAM DIMMs
• High-speed digital system clock distribution

Clock Buffers, Drivers Procurement Notes

Verify the component manufacturer, as the datasheet originates from Pericom Semiconductor Corporation. Confirm that the 'H' suffix denotes the 28-pin SSOP package and the 'E' suffix indicates Pb-free and Green compliance. Ensure the specific revision matches the required design specifications.

Clock Buffers, Drivers Selection Notes

Select this component when a 1-to-10 fanout buffer is required for SDRAM systems operating at frequencies up to 140 MHz. It is suitable for designs needing individual output control via I2C and operation within the -40°C to +85°C industrial temperature range. Ensure the PCB layout accommodates the 28-pin SSOP footprint.

Clock Buffers, Drivers Part Context

The PI6C182BHE belongs to the PI6C182B family of precision clock buffers. It was originally manufactured by Pericom Semiconductor Corporation before being acquired by Diodes Incorporated. The device serves as a specialized solution for high-speed memory clock distribution, distinct from general-purpose logic buffers.

Clock Buffers, Drivers Replacement Considerations

Direct replacement part numbers are not explicitly listed in the provided documentation. Verify compatibility with alternative 1-to-10 SDRAM clock buffers from Diodes Incorporated or other manufacturers, ensuring pinout and electrical specifications match.

Clock Buffers, Drivers FAQ

How is the Hi-Z state controlled?

The OE (Output Enable) pin controls the Hi-Z state. Pulling OE low places all outputs in a Hi-Z state. It has an internal pull-up resistor greater than 100kΩ.

What is the maximum output skew?

The maximum output-to-output skew (tSDSKW) is 250 ps at 66 MHz and 100 MHz, and 200 ps at 133 MHz.

Can the I2C interface read back data?

No, the PI6C182B acts as a slave receiver device and cannot be read back via the I2C interface.
