BTULN

Description

The Blue Top Ultra Low Noise oscillator provides superb temperature stability, ultra-low phase noise performance and excellent short term stability, commonly used in scientific instrumentation and timing systems which require the best possible stability and phase noise. The crystal is mounted in a large thermal mass which is isolated to provide the best short term stability and phase noise, typically better than –120 dBc/Hz at 1 Hz and –178 dBc/Hz at 10 kHz.  The unit is available with temperature stability to ±5E-10 over the 0 to +50°C temperature range and an aging rate as low as 1E-10 per day. An internal doubler is optional, so 5 MHz and 10 MHz outputs may be provided simultaneously. A low noise internal voltage regulator is included, which provides excellent power supply line rejection. Please consult the factory to discuss any custom specification modifications which may better suit your application.
