Powerdown.
To shut down the high-speed outputs and reduce
power consumption, hold this pin high. For normal
operation, hold this pin low.
Calibration.
To initiate an internal self-calibration, force a high-
to-low transition on this pin. (See "PLL Self-Calibra-
tion‚" on page 10.)
Note: This input has a weak internal pulldown.
Differential Clock Output.
The output clock is recovered from the data signal
present on DIN. In the absence of data, the output
clock is derived from REFCLK.
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.
