W83176R-400/W83176G-400
CURRENT MODE DIFFERENTIAL BUFFER FOR PCI EXPRESS AND SATA
1. GENERAL DESCRIPTION
The W83176R-400 supports four current mode differential Clock pair’s buffer output companion
devices to CK409 or CK410 clock generator.
The W83176R-400 provides I2C serial bus interface to program the registers to enable or disable each
clock outputs. The W83176R-400 accepts a reference clock as its input current mode differential pair’s
clock.
