DS92CK16 Datasheet | National Semiconductor

Description The DS92CK16 1 to 6 Clock Buffer/Bus Transceiver is a one to six CMOS differential clock distribution device utilizing Bus Low Voltage Differential Signaling (BLVDS) technology. This clock distribution device is designed for applications requiring ultra low power dissipation, low noise, and high data rates. The BLVDS side is a transceiver with a separate channel acting as a return/source clock. The DS92CK16 accepts BLVDS (300 m V typical) differential input levels, and translates them to 3V CMOS output levels. An output enable pin OE , when high, forces all CLKOUT pins high. The device can be used a source synchronous driver. The selection of the source driving is controlled by the Crd CLKIN and DE pins. This device can be the master clock, driving the inputs of other clock I/O pins in a multipoint environment. Easy master/slave clock selection is achieved along a backplane.
