SiTime SiT5387
The SiT5387 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 SiT5387 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.DESCRIPTION
Engineered for best dynamic performance, the SiT5387 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 SiT5387 delivers the best dynamic performance for timing stability in the presence of environmental stressors due to air flow, temperature perturbation, vibration, shock, and electromagnetic interference. The SiT5387 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. Refer to Manufacturing Guideline for proper reflow profile and PCB cleaning recommendations to ensure best performance. Block DiagramFEATURES
