We see from your search that you're looking for information on the term "Digital PLL",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release Clocking ICs reduce component numbers from
Cirrus Logic, which we summarised at the time by saying "The CS2000 offers both a clock generator feature and clock cleanup in a single IC, reducing the number of components and board space required in audio systems".
A few weeks before,
we featured the news release Video digitiser takes more onboard from
Intersil: "Device combines ease of use and high-resolution video performance to create the ideal choice for digitising analogue YPbPr video from HDTV tuners, set-top boxes, SD and HD DVDs".
In December 2004, we covered the news from Zarlink Semiconductor
concerning its ZL30108
- take a look at Digital PLL shrinks for optical line cards
which says: "The ZL30108 is billed as the world's smallest digital PLL for optical line cards operating at rates up to OC-3/STM-1".
Take a look also at the news release from Zarlink Semiconductor, Digital and analogue PLLs combine for Sonet,
as well as Digital PLLs deliver superior jitter performance from Zarlink Semiconductor,
and TDM switching family integrates Stratum 3 timing from Zarlink Semiconductor.
