SiT5157

SiT5157 60 MHz to 220 MHz, ±0.5 to ±2.5 ppm, Elite Platform Super-TCXO Description The SiT5157 is a ±0.5 ppm to ±2.5 ppm MEMS Super-TCXO that is engineered for best dynamic performance. It is ideal for high reliability telecom, wireless and networking, industrial, precision GNSS and audio/video applications. Leveraging SiTime’s unique DualMEMS® temperature sensing and TurboCompensation® technologies, the SiT5157 delivers the best dynamic performance for timing stability in the presence of environmental stressors such as air flow, temperature perturbation, vibration, shock, and electromagnetic interference. This device also integrates multiple on-chip regulators to filter power supply noise, eliminating the need for a dedicated external LDO. The SiT5157 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. The SiT5157 can be factory programmed for any combination of frequency, stability, voltage, and pull range. Programmability enables designers to optimize clock configurations while eliminating long lead times and customization costs associated with quartz devices where each frequency is custom built.
