Block Diagram Description The PI6C185-00 is a high-speed low-noise 1-7 non-inverting buffer designed for SDRAM clock buffer applications. This buffer is intended to be used with the PI6C10X clock generator for Intel Architecture-based Mobile systems. At power up all SDRAM output are enabled and active. The I2C Serial control may be used to individually activate/deactivate any of the 7 output drivers. Note: Purchase of I2C components from Pericom conveys a license to use them in an I2C system as defined by Philips. Pin Configuration BUF_IN SDATA SCLOCK I2C I/O SDRAM0 SDRAM1 SDRAM2 SDRAM3 SDRAM6 ...
