PI6C185-02BQE

Clock Buffers, Drivers Overview

The PI6C185-02B is a precision 1-to-7 non-inverting clock buffer manufactured by Diodes Incorporated. Designed for high-speed applications up to 140 MHz, it features low noise characteristics and supports up to three SDRAM DIMMs. The device operates on a 3.3V supply voltage with multiple VDD and VSS pins to minimize noise. It incorporates an I2C serial configuration interface that allows individual activation or deactivation of the seven output drivers. At power-up, all outputs are enabled and active. The component provides low skew, specified as less than 250ps between any two output clocks.

Clock Buffers, Drivers Procurement Notes

Verify package availability in 16-pin TSSOP (L) or QSOP (Q) formats. Confirm operational temperature range requirements against the specified 0°C to +70°C ambient limit. Ensure I2C bus compatibility for serial configuration. Check for updated datasheets from Diodes Incorporated as Pericom Semiconductor Corporation was the original manufacturer.

Clock Buffers, Drivers Selection Notes

Select this component when a 1-to-7 non-inverting buffer is required for SDRAM clock distribution in mobile architectures. Ensure the design accommodates the 3.3V supply voltage and utilizes the I2C interface for dynamic output control. Verify that the load capacitance per pin does not exceed 6pF to maintain timing specifications. Consider EMI reduction guidelines such as series resistors and ground plane routing.

Clock Buffers, Drivers Part Context

The PI6C185-02B belongs to the PI6C185 family of precision clock buffers. It is functionally related to other devices in the PI6C18x series, which offer varying numbers of outputs. The device was originally produced by Pericom Semiconductor Corporation before being acquired by Diodes Incorporated. It is intended to be used in conjunction with clock generators like the PI6C10X.

Clock Buffers, Drivers Replacement Considerations

Consult Diodes Incorporated documentation for direct replacements within the PI6C185 family. Verify pinout compatibility if substituting with other 16-pin clock buffers. Ensure I2C address configurations match if multiple devices are used on the same bus.
