The SM5009 series is a low crystal current crystal oscillator module IC from Nippon Precision Circuits Inc. It has excellent frequency response and built-in feedback resistors. Just connect the crystal to achieve stable 40MHz fundamental oscillation.
The SM5009 series are crystal oscillator module ICs designed to reduce crystal current below existing products by incorporating a low crystal current type oscillating circuit. The integrated oscillating circuit includes oscillator capacitors with excellent frequency response and a feedback resistor, allowing for stable fundamental oscillation up to 40MHz simply by connecting the crystal.
These devices are ideal for SMD type crystal oscillators using strip-shaped crystal blanks. They support both CMOS and TTL output levels and offer various operating voltage ranges (2.7V to 5.5V) with optional standby functions to stop or inhibit the oscillator.
| Operating frequency range | Up to 40MHz |
|---|---|
| Supply voltage (3V operation) | 2.7 to 3.6V |
| Supply voltage (5V operation) | 4.5 to 5.5V |
| Operating temperature range | -40 to +85 °C |
| Output load capacitance (max) | 50pF |
| Package type | 8-pin SOP or Chip form |
The SM5009 series supports fundamental oscillation responding up to 40MHz.
Yes, it includes oscillator capacitors Cg and Cp built-in.
When INH goes LOW, the oscillator stops and the output becomes high impedance.
