Block Diagram Description
Phase Frequency Detector and Filter
These two blocks accept input signals from the reference frequency
(REF) input and the feedback (FB) input and generate correction
information to control the frequency of the Voltage-Controlled
Oscillator (VCO). These blocks, along with the VCO, form a Phase-
Locked Loop (PLL) that tracks the incoming REF signal.
VCO and Time Unit Generator
The VCO accepts analog control inputs from the PLL filter block
and generates a frequency that is used by the time unit generator to
create discrete time units that are selected in the skew mix matrix.
The operational range of the VCO is determined by the FS control
pin. The time unit (t
U
) is determined by the operating frequency of
the device and the level of the FS pin as shown in Table 1.
Skew Select Matrix
The skew select matrix is comprised of four independent sections.
Each section has two low-skew, high-fanout drivers (xQ0, xQ1),
and two corresponding three-level function select (xF0, xF1)
inputs. Table 2 shows the nine possible output functions for each
section as determined by the function select inputs. All times are
measured with respect to the REF input assuming that the output
connected to the FB input has 0t
U
selected.
