The SY89420V device consists of two identical, low
jitter, digital Phase Locked Loops based on Micrel-Synergy's
differential PLL technology. Each of the PLLs (PLLA and
PLLB) is capable of operating in the 30MHz to 560MHz
input reference frequency range independently of the other
and is configurable separately. The PLLs can be configured
to be matched in all regards, or can be configured so that
PLLB is used as a frequency doubler, while PLLA is used
to regenerate the undoubled frequency.
Two reference inputs (RINX and RINX), two feedback
inputs (FINX and FINX), two filter pins (F1X and F2X) and
two differential outputs (FOUTX and FOUTX) are provided
for each of the two PLLs. The reference and feedback
inputs can be used as either differential or single-ended
inputs. In single-ended mode RINX and FINX can be
connected to either VBB for normal 100K PECL levels or
VTH for normal TTL levels.
Feedback for the loops is realized by connecting FOUTX,
FOUTX to FINX, FINX by means of external circuitry. This
allows the user the flexibility of inserting additional circuitry
off-chip in the feedback paths, such as a divider. Pulldown
resistors are required for the FOUTX and FOUTX pins.
Use of a phase-frequency detector results in excellent
PLL locking and tracking characteristics. Error correction
voltages are generated by the detector if either phase or
frequency deviations occur. The VCO has a frequency
range covering more than a 2:1 ratio from 480MHz to
1120MHz.
Select pins S1X and S2X are used to program the N
dividers for optimum VCO operation, in other words with
the VCO in the center of its range. Additional select pins,
S3B and S4B, are provided for PLLB. When both S3B and
S4B are low, PLLB is identical to PLLA. When S3B is high,
NB can be set to 1, 10, 18, or 20. When S4B is high, the
frequency doubler option is enabled (P = 2). All Select pins
are TTL compatible.
