These unique OCXOs and OCVCXOs
provide frequency stabilities in the range of
10 ppb to 50 ppb, over the commercial,
extended commercial or the industrial
temperature range. Power requirements are
1.1W over the commercial temperature range
and 1.5W over the industrial temperature
range after warm-up. Additionally, excellent
aging is achieved through the use of
overtone SC cut crystals.
Features
• Frequency Range: 5 to 40 MHz
• OCXO - Fixed Frequency
• OCVCXO - Voltage Controlled Frequency
• 3.3 Vdc or 5.0 Vdc Operation
• Available Frequency Stabilities:
±10.0 ppb, ±±0 ppb or ±50 ppb
• Available Temperature Ranges:
0 to 70°C, -±0 to 70°C, -±0 to 75°C,
-40 to 70°C or -40 to 85°C
• Low Phase Noise / Phase Jitter
• Output: CMOS Logic or Sinewave
• SMT Package: ±± mm x ±5 mm x 1±.7 mm
• RoHS Compliant / Lead Free
The OH300 series is available with
CMOS logic or Sinewave output along
with Electronic Frequency Tuning. These
oscillators provide outstanding phase
noise that varies depending on frequency
requirements. Allan Variance specifications
are rated for primary reference standards.
Warm up times are on the order of 5 minutes
to 0.10 ppm of final frequency.
