SiT5156 1 MHz to 60 MHz, 0.5 to 2.5 ppm, Elite Platform Super-TCXO Description Features The SiT5156 is a 0.5 ppm to 2.5 ppm MEMS Super- Any frequency from 1 MHz to 60 MHz in 1 Hz steps Factory programmable options for short lead times TCXO that is engineered for best dynamic performance. It is ideal for high reliability telecom, wireless and networking, Best dynamic stability under airflow, thermal shock industrial, precision GNSS and audio/video applications. 0.5 ppm stability across temperature 15 ppb/C typical frequency slope (F/T) Leveraging SiTimes unique DualMEMS temperature -40C to +105C operating temperature sensing and TurboCompensation technologies, the No activity dips or micro jumps SiT5156 delivers the best dynamic performance for timing Resistant to shock, vibration and board bending stability in the presence of environmental stressors such as On-chip regulators eliminate the need for external LDOs air flow, temperature perturbation, vibration, shock, and 2 Digital frequency pulling (DCTCXO) via I C electromagnetic interference. This device also integrates Digital control of output frequency and pull range multiple on-chip regulators to filter power supply noise, Up to 3200 ppm pull range eliminating the need for a dedicated external LDO. Frequency pull resolution down to 5 ppt 2.5 V, 2.8 V, 3.0 V and 3.3 V supply voltage The SiT5156 offers three device configurations that can be LVCMOS or clipped sinewave output ordered using Ordering Codes for: RoHS and REACH compliant Pb-free, Halogen-free, Antimony-free Applications Precision GNSS systems Microwave backhaul Network routers and switches The SiT5156 can be factory programmed for any Professional audio and video equipment combination of frequency, stability, voltage, and pull range. Storage and servers Programmability enables designers to optimize clock Test and measurement 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.
