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.

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 V

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.

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.

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,

frequency doubler option is enabled (P = 2). All Select pins

are TTL compatible.
