To handle the increase in mobile traffic driven by smart phones, tablets and increasing video streams, carriers are switching to Synchronous Ethernet. The International Telecommunications Union (ITU) and IEEE created Sync E and IEEE 1588v2 timing standards to insure interoperability in this new packet-based network. MtronPTI’s XO5x84-1588-R Series OCXO (Oven Controlled Crystal Oscillator) is specifically designed and tested for Sync E and 1588v2, has very low wander generation and is available in 10 MHz, 12.8 MHz and 20 MHz versions.
PDI’s LV5 and PE5 series of miniature oscillators come in 3.2mm x 5mm ceramic packages. Their size and low jitter (0.2pS for the LV5 and 0.3pS for the PE5) over the telecommunication industry standard carrier offset of 12kHz to 20MHz makes them ideal for telecom clocking applications.
The T1241 TCXO by Greenray Industries stands out from other temperature compensated crystal oscillators due to its excellent phase noise and low-g sensitivity (down to <7 x 10-11/g). Its vibration compensated package makes it ideal for mobile applications in which the TCXO will need to perform under conditions of vibration or shock.
This frequency source is used for calibration and covers the 25 to 3000 MHz frequency range. It has <1ppm frequency stability, > -10dBm output power, >30dB controlled range output power, >40dBc spurious rejection, and a 100 MHz external and internal reference clock. For additional information on its specifications, download the datasheet.
Phonon has been producing an extensive legacy of space-qualified SAW devices since 1987. All products are built to each customer’s individual requirements. Products can be built for either commercial or military space applications. Our space-qualified products are all built to MIL-PRF-38534 Class K reliability.
This frequency source covers the 3 to 18 GHz frequency range and features a self-checking function, a controlling power supply, and signal control. It has a 1 kHz frequency step, >10dBm output level, <3dB amplitude flatness at room temperature (<5dB at high and low temperatures), >50dB stray rejection, and >40dB harmonic rejection. For more information on its electrical and mechanical specifications, download the datasheet.
This oscillator features high stability, a 25 MHz to 150 MHz operating frequency, an HCMOS output, and a -55 oC to +125 oC operating temperature range. It’s ideal for harsh environments with high and low temperatures and high vibration and is particularly well suited for avionics manufacturers due to its tight tolerance with temperature and low drift over a long lifetime.
This ovenized voltage controlled SAW oscillator (VCSO) is extremely effective and reliable in applications involving use of analog signal processing, such as radar, communications, and electronic warfare (EW). Addition of a micro-oven to the design yields superior temperature stability (just +/- 10ppm over temperature range -40C to 85C). Specific emphasis on low phase noise, from the start of the design process, has led to a SAW oscillator of superior performance and quality.
