Antimony-free
For AEC-Q100 oscillators, refer to SiT8924 and SiT8925
Applications
Ideal for DSC, DVC, DVR, IP CAM, Tablets, e-Books,
SSD, GPON, EPON, etc
Ideal for high-speed serial protocols such as: USB,
SATA, SAS, Firewire, 100M / 1G / 10G Ethernet, etc.
Electrical Characteristics
All Min and Max limits are specified over temperature and rated operating voltage with 15 pF output load unless otherwise
stated. Typical values are at 25°C and nominal supply voltage.
