Optical Modules
With massive internet traffic growth, data centers are increasing throughput, placing a greater demand on modules to deliver faster data rates – making timing margin more important. At the same time these modules are used in hotter, smaller spaces making power and size a critical factor.
SiTime MEMS differential oscillators are ideal for 100G to 800G optical modules. They offer breakthrough 70-fs jitter, the smallest differential package, excellent immunity to power supply noise and environmental hazards, low-power options, and wide temperature operation.
