**Crystal Clock Oscillator Specification** _Part No. + Packaging:_ _**LFSPXO064157Cutt**_ 

## **Description** 

- Standard 2.5 x 2.0 oscillator in a ceramic package with a hermetically sealed metal lid. 

- Model 

- Model Issue number 

## IQXO-791 

- 2 

## **Frequency Parameters** 

- Frequency 40.0MHz Frequency Stability ±25.00ppm 

- Operating Temperature Range -20.00 to 70.00°C Ageing ±3ppm max per year @ 25°C 

## **Electrical Parameters** 

- Supply Voltage 

   - 3.3V ±10% 

- Current Draw 20.000mA 

## **Output Details** 

- Output Compatibility 

HCMOS 

## **Outline (mm)** 

- Drive Capability 15pF Rise and Fall Time 7.0ns max Duty Cycle 40/60% Output Voltage Levels: Output Low (VoL): 10%Vs max 

- Output High (VoH): 90%Vs min 

- Start Up Time: 10ms max 0.7ms typ to 90% of final amplitude (under ideal conditions @ 25°C) 

## **Output Control** 

- Enable/Disable: 

- Logic ‘1’ (≥70% Vs) to pad 1 enables oscillator output. Logic ‘0’ (≤30% Vs) to pad 1 disables oscillator output; when disabled the oscillator output goes to the high impedance state. 

No connection to pad 1 enables oscillator output. 

- Stand-by Current: 10μA max, 1.0µA typ @ 25°C 

## **Noise Parameters** 

- Period Jitter (pk-pk): ±80ps typ 

- Period Jitter (1σ): ±10ps typ 

- Phase Jitter (12kHz to 20MHz): 1ps rms max 

## **Environmental Parameters** 

- Storage Temperature Range: -55 to 125°C 

- Mechanical Shock: MIL-STD-883, Method 2002, Condition B (or comparable). 

- Vibration: MIL-STD-883, Method 2007, Condition A (or comparable). 

## **Manufacturing Details** 

- Note: Do not connect inductor or bead between pad 2 and GND as it can make the output unstable. 

- RoHS Terminations 

- RoHS Reflow Temp 

260°C max for 10secs max
