DATA SHEET
ASSP for DTS
Piezoelectric VCO
(6 to 30 MHz)
M3 Series (E100)
■
■■
■DESCRIPTION
The M3 series (E100) of VCO (Voltage Controlled Oscillator) apply to the frequency range 70-300 MHz.
The M3 series uses a single lithium tantalate piezoelectric crystal (LiTaO3) that has large electromechanical
coupling coefficient, and a unique SAW resonator. That provides wide bandwidths, and exceptional stability in
VHF band until 300MHz.
■
■■
■FEATURES
• Frequency range: 70 to 300MHz
• Wide frequency controllable range: Over than ±1600 ppm (0.5 to 4.5 V)
• Excellent temperature stability: ±200 ppm or less (-10 to 70 °C)
• No adjustment is required due to high accuracy oscillation frequency (±300 ppm or less)
• Highly reliable hermetically sealed package
• High carrier noise ratio: -90dB or less (Detuning;12.5kHz, bandwidth; 8kHz)
• Small type, and compatible with 8-pin DIP IC

■ABSOLUTE MAXIMUM RATINGS
WARNING: Piezoelectric devices can be permanently damaged by application of stress (voltage, current,
temperature, etc.) in excess of absolute maximum ratings. Do not exceed these ratings.
■
■■
■RECOMMENDED OPERATING CONDITIONS
WARNING: The recommended operating conditions are required in order to ensure the normal operation of the
piezoelectric device. All of the device’s electrical characteristics are warranted when the device is
operated within these ranges.
Always use piezoelectric devices within their recommended operating condition ranges. Operation
outside these ranges may adversely affect reliability and could result in device failure.
No warranty is made with respect to uses, operating conditions, or combinations not represented on
the data sheet. Users considering application outside the listed conditions are advised to contact their
FUJITSU representatives beforehand.
