Cost effective alternative to rubidium
Designed for wireless base stations,MSC’s new MD-023 extended holdover crystal oscillator (EHXO) from Vectron International is said to offer cost savings up to 50 per cent compared with conventional, high-stability rubidiumoscillators.
Frequency temperature stability is 0.1ppb from zero to 70°C.
Phase noise, depending on frequency offset, is -125dBc/Hz at 100 Hz offset and -145dBc/Hz at 10 kHz offset. Aging is a maximum of 0.08ppb/day.
TheMD-023 is said to provide holdover precision of 6μs for 24h
over a 10°C temperature change. Compared with traditional high stability references, theMD-023 is said to offer a low phase noise output signal of 10.0MHz and a 1pps output at half the cost and with reduced power consumption. The devicemeasures 76.2 by 76.2 by 25.4mmand communication via a serial communications interface.

Tiny oscillator is energy efficient
Epson Toyocom’s new EG-2121/2102CB series differential-output SAW oscillators are believed to be the world’s smallest. Measuring 5.0 by 3.2 by 1.4mmthe devices have a 50 per cent smaller footprint than their predecessors. Samples are available. Commercial availability is scheduled for December 2011.
Devices in the EG-2121/2102CB series oscillate at fundamental
frequencies ranging from100MHz to 700MHz. They support 2.5V and 3.3V LVDS and LV-PECL output and consume approximately 50 per cent less power than their predecessors.
These oscillators use a SAWresonator engineered to resist
oscillation defects induced by particles and other foreign substances, while a built-in low-noise regulator helps them withstand fluctuations in external power supply.
These characteristics suit high-capacity, high-speed
communications systems.
