External Bias Resistor.
This resistor is used by onboard circuitry to estab-
lish bias currents within the device. This pin must
be connected to GND through a 10 kΩ (1%) resis-
tor.
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 11)
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 and data
recovery. Additionally, the reference clock is used to
derive the clock output when no data is present.
Loss-of-Lock.
This output is driven high when the recovered clock
frequency deviates from the reference clock by the
amount specified in Table 4 on page 7.
Differential Data Input.
Clock and data are recovered from the differential
signal present on these pins.
