Start with the news release Pentek releases clock synthesiser PMC module from Pentek, which we summarised at the time by saying "Pentek has released the user-configurable Model 7191 programmable clock synthesiser PMC module, which is suitable for use in laboratory systems or field-configurable deployed applications.". Several months prior to that, we featured the news release Silicon Labs introduces jitter cleaning clock IC from Silicon Laboratories: "Silicon Laboratories has introduced a frequency-flexible timing IC solution for networking and telecoms applications that require jitter attenuation for clock signals without clock multiplication.".
 
In April 2010, we covered the news from Ecliptek - take a look at Ecliptek adds VCMOs to frequency control range which says: "Ecliptek has added the EMVA12 (2.5VDC) series and EMVA13 (3.3VDC) series of voltage-controlled MEMS oscillators (VCMOs) to its frequency control product line.".
 
Take a look also at the news release from Silicon Laboratories, Silicon expands precision clock broadcast range, as well as Euroquartz unveils HCMOS Xpresso oscillators from Euroquartz, and Oscillators focus on noise-reduction technologies from Fox Electronics.
