SIT5156AICFK-33N0-10.000000

The SiT5156 Super-TCXO is a highly flexible, tight-stability oscillator for high-reliability systems in industrial, server and storage, networking, and telecom. Based on SiTime’s unique DualMEMS™ temperature sensing and TurboCompensation™ technology, this device delivers excellent dynamic performance in the presence of common environmental hazards, such as airflow, temperature perturbation, vibration, shock, power supply noise, and electromagnetic interference (EMI). The SiT5156 can be factory-programmed to any combination of frequency, stability, voltage, and pull range. This programmability enables designers to customize MEMS TCXO configuration for best system performance while eliminating the long lead time and customization costs associated with quartz devices. This device also integrates multiple on-chip regulators, providing power supply noise filtering and eliminating the need for a dedicated external LDO. SiT5156 oscillators are ideal for high-reliability telecom, wireless and networking, industrial, precision GNSS, and audio/video applications.Block Diagram<strong>Features:</strong> Any frequency between 1 MHz and 60 MHz in 1 Hz steps, Excellent dynamic stability under airflow and rapid temperature change, ±500 ppb overtemperature stability, ±15 ppb/°C frequency slope (ΔF/ΔT), 3e-11 ADEV at 10 second averaging time, -40°C to +105°C operating temperature, No activity dips or micro jumps, Resistant to shock, vibration, and board bending, Up to ±3200 ppm pull range (VCTCXO or DCTCXO), Digital frequency pulling (DCTCXO) via I2C, Digital control of output frequency and pull range, Frequency pull resolution as low as 5 ppt (0.005 ppb), 2.5 V, 2.8 V, 3.0 V, and 3.3 V supply voltage, On-chip regulators, eliminating the need for the external LDO, LVCMOS or clipped sinewave output, RoHS and REACH compliant, Pb-free, halogen-free, and antimony-free, Precision GNSS, Microwave backhaul, Network switches and routers, Professional audio and video equipment, Storage and servers, Test and measurement
