Clock Input for DATAP/N. Buffer is powered down when
ENDATCKN = 1.
External DATCKP/N Clock Select (Active-Low). Selects
external DATCKP/N clock to demultiplexer.
0 = select DATCKP/N
1 or no connection = select VCO clock
Data Input for CML. Use this input for system loopback
data when LAINP/N is used.
Enable DATAP/N Inputs (Active-Low). Selects DATAP/N
as data source rather than limiting amplifier output.
0 = select DATAP/N
1 or no connection = select LAINP/N
Adjustable Sampling Circuit Reference Resistor.
Connect a 2.1 k
Adjustable Sampling Time Control Inputs. AST[4:0]
allows introduction of an offset into the sampling time. The
most significant bit (A4) is the sign bit and bits A[3:0]
represent the magnitude. (See the Decision Circuit—
Adjustable Sampling Time (ASTREF, AST[4:0]) section,
page 15.)
A4 is the polarity bit as follows:
1 = advance
0 = delay sampling point
AST[3:0] provides adjustments in steps (increments or
decrements) of 6.25 ps in the sampling instant.
