SiT5721 series
SiTime's SiT5721 series is an OCXO that works as the most stable clock source against environmental stresses such as ambient temperature fluctuations, vibration, shock, and electromagnetic interference (EMI). In addition, digital frequency tuning using I2C is possible. This reduces board noise.
OCXO is an abbreviation for Oven Controlled Crystal Oscillator and is also called a constant temperature oven type oscillator. This product group boasts better stability than general-purpose oscillators and TCXOs.
