OCXO - Oven Controlled Crystal from SiTime

SiTime, Emerald OCXO, 1-60MHz, Str 3E, +/-5ppb, 9x7mm, 14x9mm

Status: Standard | Data Sheet:

| RoHS Compliance: Rohs Compliant

The SiTime SiT5711 is the industry’s smallest Stratum 3E OCXO with ±5 ppb frequency stability and 50 ppt/°C frequency slope (ΔF/ΔT). This device is engineered to provide the best dynamic performance. Leveraging SiTime’s unique DualMEMS™ and TurboCompensation™ temperature sensing technology, this OCXO delivers the most stable timing in the presence of environmental stressors such as airflow, temperature perturbation, vibration, shock, and electromagnetic interference (EMI).

The environmental robustness of SiT5711 enables unmatched ease-of-use and simplifies system design:

Can be placed anywhere on the PCB
No mechanical cover or shielding needed for thermal isolation
No external regulators required
No additional sealing needed for high humidity environments

The SiT5711 can be factory-programmed to any frequency between 1 and 60 MHz. In addition to the 9 x 7 mm package (the smallest OCXO available), this device is also available in common OCXO footprints such as 25 x 22 mm, 20 x 13 mm, and 14 x 9 mm to enable drop-in replacement of legacy quartz OCXOs.

Features & Benefits:

10 times better dynamic stability under airflow and fast temp. ramp, ensures best system performance in harsh environments

±5 ppb over-temp. stability
2e-11 ADEV at 10 sec under airflow
±50 ppt/°C frequency slope (ΔF/ΔT)

Unmatched ease-of-use, simplifying system design

No restrictions on PCB placement
No mechanical shielding needed for thermal isolation
Resistant to humidity
No external regulator needed

Smallest size, ideal for high density and small form factor systems

9 x 7 mm footprint, 75% smaller
6.5 mm height, 40% thinner

20 times better vibration resistance, ideal for outdoor pole mounted equipment

Resistant to microphonic and/or board bending effects, ideal for large telecom PCBs

Programmable platform eliminates long lead times and customization cost associated with legacy quartz OCXO

Any frequency from 1 to 60 MHz
LVCMOS or clipped sine-wave outputs

On-chip regulators, no need for external LDOs or ferrite beads

Semiconductor-level quality and reliability, batch to batch consistency

No activity dips or micro jumps

Applications:

SONET/SDH Stratum 3E
4G/5G RRH, DU
Base Stations
Core and edge routers
Carrier class switches
IEEE 1588 boundary clocks
IEEE 1588 grandmasters
GNSS disciplined timing modules
Instrumentation
Power & Energy
Defense & Aerospace
