3V BLVDS 1 to 6 Clock Buffer/Bus Transceiver
General 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 requir-
ing 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 LVDS (300 mV typical) differential
input levels, and translates them to 3V CMOS output levels.
An output enable pin OE , when high, forces all CLK
high.
The device can be used as a source synchronous driver. The
selection of the source driving is controlled by the CrdCLK
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 back-
plane.
