... SDATA I/O SCLOCK 06-0256 Description The PI6C182 is a high-speed low-noise 1-to-10 noninverting buf- fer designed for SDRAM clock buffer applications, supporting frequencies up to 110 MHz. At power up all SDRAM output are enabled and active. The I serial control may be used to individually activate/deactivate any driver. ...

... The I C interface permits individual enable/disable of each clock output and test mode enable. The PI6C182 is a 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. Each byte on the SDATA line must be 8-bits long (MSB first), fol- lowed by an acknowledge bit generated by the receiver ...
