OCXO Specification
IQOV-74
ISSUE 1; January 2016
Description
Outline (mm)
The IQOV-74 Oven Controlled Crystal Oscillator (OCXO) is
from the world's first ASIC-based OCXO family using patented
ASIC technology. This Stratum 3 compliant oscillator delivers
stability as low as ±10ppb over -20 to 70°C and is capable of
short-term ageing typically less than ±2ppb/day. The highly
integrated oven ensures short warm-up times and low power
consumption of typically 350mW at room temperature. The
ASIC architecture delivers 1000x reliability improvement
compared to traditional OCXOs and is available in a 14pin-DIL
package.

Type 111 Fig 2 (≤10ns), oscillator stabilised 24hrs at constant
temperature (±1°C, still air), data collected over 100000secs at
1sec intervals (-3dB cut-off, 2nd order high pass loop filter).
Note:
Parts should be shielded from drafts causing unexpected
thermal gradients. Temperature changes due to ambient air
currents can lead to short term frequency drift.
The characteristics of the component may be temporarily
affected by the processes of assembly and soldering. The
frequency specifications apply 48hrs after assembly. Nominal
conditions apply unless otherwise stated.
