... I/O SCLOCK 08-0298 Description The PI6C185- 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 genera- tor for Intel Architecture-based Mobile systems. At power up all SDRAM output are enabled and active. The I Serial control may be used to individually activate/deactivate any of the 7 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. To change one of the control bytes, all preceding bytes must be sent. Every bite put on the SDATA line must be 8-bits long (MSB first), followed by an acknowledge bit generated by the receiving device ...
