SiTime Corporation announced the availability of a significant new feature of the SiTime Endura SiT5146 Super-TCXO. Previously, these devices operated down to -40°C, but now support -55°C. With this new capability, the SiT5146 delivers best-in-class stability over -55ºC to +105ºC, benefiting airborne applications such as low earth-orbiting (LEO) satellites, commercial aircraft, satellite communication systems, and rocket delivery systems as well as terrestrial systems residing in extremely cold environments. The SiTime Endura SiT5146 is a ruggedized ±1 to ±2.5 ppm MEMS Super-TCXO that is available in two flavors of acceleration sensitivities: 0.009 ppb/g and 0.1 ppb/g. It can withstand high levels of shock and vibration while continuing to deliver outstanding performance. Frequencies are programmable with 6 decimals of accuracy from 1 MHz to 60 MHz. Offered in a 5.0 mm x 3.2 mm package, the SiT5146 can be factory programmed for any combination of frequency, stability, voltage, and pull range, enabling shorter lead times. The device is available now in production quantities.
