SiTime SiT5357
The SiT5357 is a ±100 ppb precision MEMS Super-TCXO that is fully compliant to Telcordia GR-1244-CORE Stratum 3 oscillator specifications. This device also integrates multiple on-chip regulators to filter power supply noise, eliminating the need for a dedicated external LDO. The SiT5357 offers three device configurations that can be ordered using Ordering Codes for: 1) TCXO with non-pullable output frequency, 2) VCTCXO allowing voltage control of output frequency, 3) DCTCXO enabling digital control of output frequency using an I2C interface, pullable to 5 ppt (parts per trillion) resolution.- Min Voltage : 2.97V
- Max Voltage : 3.63V
- Max Operating Temp : 85°C
- Min Operating Temp : -40°C
