Model 148  
OCXO Ultra Low Power, shock resistant  
Features  
. 8 to 100 MHz Frequency Range  
. Fast warm-up time  
. ECO-friendly, <250 mW power consumption  
. HCMOS output  
Applications  
. Airborne and ground mobile  
. PLL reference  
Part Dimensions: 16 × 15.3 x 10.5 mm  
. Battery powered applications  
Description  
The Model 148 is a high stability, low power OCXO that utilizes an SC-cut quartz resonator. The SC resonator insures  
excellent phase noise and low aging rates. The novel design featuring the oscillator and oven control circuitry inside of the  
vacuum-sealed TO-8 crystal enclosure provides reduced size, fast warm-up, and excellent temperature stability. In addition  
to improved performance characteristics, the compact design of Model 148 offers increased resilience to mechanical shock  
and vibration.
