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 LVDS (300 mV 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 as a source synchronous

driver. The selection of the source driving is

controlled by the CrdCLKIN 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.
