... SDATA I/O SCLOCK Description The PI6C185- high-speed low-noise 1-5 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 outputs are enabled and active. The I Serial control may be used to individually activate/deactivate any of the 5 output drivers ...

... The I C interface permits individual enable/disable of each clock output and test mode enable. The PI6C185- slave receiver device. It can not be read back. Sub-addressing is not supported. All preceding bytes must be sent in order to change one of the control bytes. Every bite put on the SDATA line must be 8-bits long (MSB first), followed by an acknowledge bit generated by the receiving device ...
