REXT
External Bias Resistor.
This resistor is used by onboard circuitry to establish
bias currents within the device. This pin must be
connected to GND through a 10 k
Ω (1%) resistor.

2.5 V
Supply Voltage.
Nominally 2.5 V.

GND Pad
GND
Supply Ground.
Nominally 0.0 V. The GND pad found on the bottom
of the 20-pin micro leaded package (see Figure 12)
must be connected directly to supply ground.

Differential Reference Clock.
The reference clock sets the initial operating fre-
quency used by the onboard PLL for clock regenera-
tion and multiplication. Additionally, the reference
clock is used as a reference in generation of the LOL
output and to bound the frequency drift of MULTOUT
when CLKIN is not present.
6LOL

LVTTL
Loss of Lock.
This output is driven high when a divided version of
the clock multiplier output deviates from the refer-
ence clock frequency by the amount specified in

Differential Clock Input.
Differential input clock from which MULTOUT is
derived.
