Silicon Labs has introduced a family of small crystal oscillators (2.5 x 3.2mm option) and voltage-controlled crystal oscillators (VCXOs) for applications that require low jitter and frequency-flexible clock synthesis. Si54x/6x ‘Ultra’ oscillators can have jitter as low as 80fs “providing jitter margin for applications including data centre interconnect, optical transport, broadcast video, test and measurement”, ...
