1000C
1000C Ultra High Performance Crystal Oscillator OCXO
Overview
Microsemi 1000C is an ultra high performance crystal oscilator (OCXO) that achieves low phase noise, excellent short term stability and low aging rates by utilizing state-of-the-art SC cut quartz crystal resonators.The 1000C OXCO delivers extremely low aging rates, superior temperature stability, low phase noise, four independently buffered and transformer isolated outputs and linearized electronic frequency control for fine frequency tuning. The oscillator has electronic tuning input of 0V to 10V range with the oscillator frequency centered at +5V. Tuning range is typically 6.0E-7 (positive slope). The product is offered in two versions--High Performance and Ultra High Performance.
Low Aging Rates
Using high-performance SC-cut quartz crystal resonators, the 1000C exhibits aging rates as low as 5E-11 per day (typical) after years of continuous operation. The specified aging is reached within 30 days of continuous operation, and continues to improve over time.Superior Temperature Stability
A dewar-insulated oven provides superior temperature stability over the full temperature range. The maximum frequency change over the operating temperature range is <5E-9. An oven temperature indicator (10mV per degree C) is provided at the power connector.Low Phase Noise
The High performance phase noise version of the oscillator circuit produces phase noise of -120 dBc at 1 Hz and -160 dBc at 100 kHz. The Ultra High Performance version of the oscillator circuit produces phase noise of -130 dBc at 1 Hz and -160 dBc at 100 kHz. Low noise, high isolation buffer amplifiers provide four independent 5 MHz outputs. The buffer amplifiers isolate outputs from load variations. An internal voltage regulator minimizes fluctuations due to power supply ripple.Fine Frequency Tuning
Linearized electronic frequency control allows the use of servo loop techniques for fine frequency tuning. Linearity is better than 5% over the specified tuning range.Key Features
