Description
1.25 MHz to 40 MHz
MF Electronics EE (SMD) VCTCXOs are
miniature oscillators with many configura-
tions. They have various frequency ranges
between 1.25 MHz to 40 MHz, and are
ideal for high volume, low cost applications.
FEATURES
• Low power, low voltage
• ±5 ppm or ±10 ppm min is controlled by external voltage
• ±3 ppm min is controlled mechanically
• Four stability choices — from ±1 to ±5 ppm
• Guaranteed start-up with ramping DC Supply
• Choice of two supply voltages — 3.3V or 5.0V
• Choice of two output waveforms — Clipped Sine or HCMOS
Many choices of stability and temperature
are possible, resulting in the optimum
cost-performance tradeoff. Mechanical
control is standard, with optional elec-
tronic control, allowing the frequency to
be set or track to a reference frequency.
TYPICAL APPLICATIONS
HCMOS output may be chosen to drive
logic devices, but when clipped sine
wave is used, the current is less than
2.5 mA. The oscillators are furnished in
tape and reel for automated production.
• Ideal for battery powered equipment
• Recommended for portable, mobile, wireless equipment
