DS04-21703-3E
Piezo Electric VCO
M2 Series (D110)
VOLTAGE CONTROLLED OSCILLATOR (4 to 30 MHz)
s DESCRIPTION
The M2 series (D110) Voltage Controlled Oscillators (VCO) directly oscillate in the frequency range of 4 to 30 MHz.
The M2 series VCO use a piezoelectric single crystal with high electromechanical coupling coefficient (LiTaO3: lithium
tantalate) for stable and wide variable frequency width.
Excellent S/N and jitter characteristic due to high Q of lithium tantalate can realize high quality playback sound and
picture, especially in PLL circuit of digital audio and video equipments.
s FEATURES
• Wider variable frequency width than quarts crystals: ±0.2% or more
• High stability (100 times more stable than LC or TTL-IC VCO)
• Excellent S/N and jitter characteristic due to high Q of lithium tantalate for high quality playback sound and
picture.
• Excellent temperature characteristic: –300 ~ 500 ppm (–10 ~ +70°C)
• 10-pin SIP ready for high-density mounting.
