KVG has released the new VCXO/TCXO TO-900 series in a small 14 x 9 mm SMD package.
The devices fulfil the holdover stability requirements according to ANSI clock specifications Stratum 3 Telcordia (Bellcore) 1244-CORE, ie, frequency dependency from temperature is smaller than ±0,28 ppm, required 24 hours holdover stability is better than ±0,32 ppm. Overall stability, including 20 years ageing, is better than ±4,6 ppm. These performance figures are achieved by the combination of a new TCXO-ASIC with a digitally controlled analog 5th order compensation and the use of highly stable crystals.
The oscillator may also be supplied as a VC-TCXO with a pulling range of up to ±10 ppm. The possible frequency range is between 10 and 40 MHz; typical standard frequencies are 10 MHz, 12,8 MHz, 16,384 MHz, 19,44 MHz, 20 MHz and 25 MHz. Typical phase noise is -145 dBc/Hz at 1 kHz distance from the carrier at 10 MHz oscillator frequency. Supply voltage can be chosen between +5 V or +3,3 V. Possible output signals are either clipped sine wave or HCMOS.
Typical applications are network and synchronisation components and systems for professional telecommunication, as well as measurement equipment and systems for net monitoring. The new oscillators are ROHS-compliant and can be used in lead-free soldering processes.
