GENERAL DESCRIPTION The W83176R-401 supports eight current mode differential Clock pair’s buffer output companion devices to CK409 or CK410 clock generator. The W83176R-401 provides I2C serial bus interface to program the registers to enable or disable each clock outputs. The W83176R-401 accepts a reference clock as its input current mode differential pair’s clock. 2. PRODUCT FEATURES • • • • • • • • • Eight current mode differential clock pairs clock outputs Support zero delay buffer mode and normal buffer mode Supports every clock pairs hardware output enable/disable pin Programmable PLL bandwidth Support PLL or NORMAL mode buffer output Low Skew outputs (< 50ps) Low cycle to cycle jitter (
