REXT
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 k
1resis-
tor.

REFCLK–
ISee Table 2
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.

O
LVTTL
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.

OCML
Differential Data Output.
The data output signal is a retimed version of the
data recovered from the signal present on DIN. It is
phase aligned with CLKOUT and is updated on the
rising edge of CLKOUT.
