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 kΩ (1%) resistor.
Supply Voltage.
Nominally 2.5 V.
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.
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
Table 4 on page 8.
Differential Clock Input.
Differential input clock from which MULTOUT is
derived.
