Micro Analog Systems, Finland, introduces the MAS9279, a VCTCXO IC, with fourth order compensation and frequency range from 10MHz up to 52MHz. With a CMOS output, the IC is ideal for Stratum-3 products as well as for other high-end VCTCXO and TCXO modules.
Due to its extremely small size it is suitable even for miniature oscillator modules such as those with dimensions down to 5 by 3.2mm square. The IC allows the use of overtone crystals and features an optional divider function.
The MAS9279 has a very low phase noise of less than -140 dBc/Hz at 1 kHz at 19.44MHz, making the device ideal for use in high end VCTCXO and TCXO modules. For high-end applications the crystal offset can be trimmed to typically less than ±0.1ppm. Compensation accuracy is better than ±0.28ppm from 0°C to +50°C and better than ±0.75ppm from -20°C to +70°C.
The product is delivered as die or in plastic packages like QFN and samples are available now.
