About VIO Pin Settings - 1) In order to output the clock from the oscillator supply voltage should be connected to VCC and VIO pins. For 1.2 V ≤ VCC < 1.5 V, set VIO = VCC; otherwise, VCC do not need to be equal to VIO 2) As shown in the timing chart above, the output level of the clock output from the OUT pin can be controlled by changing the voltage level applied to the VIO pin. VIO voltage level = clock output level. 3) VIO pin can also be used as an OE (Output enable) pin. When VIO = 0 V, the output is disabled. If VCC is supplied, the internal oscillation circuit will be in operating, and the clock output can be obtained without having to wait for the VIO power to be restored.

Handling Precautions Prior to using this product, please carefully read the section entitled “Precautions” on our Web site (https://www5.epsondevice.com/en/information/#precaution) for instructions on how to handle and use the product properly to ensure optimal performance of the product in your equipment. Before using the product under any conditions other than those specified therein, please consult with Epson to verify and confirm that the performance of the product will not be negatively affected by use under such conditions. In addition to the foregoing precautions, in order to avoid degrading the performance of the product, we strongly recommend that you DO NOT use the product under ANY of the following conditions: (1) Mounting the product on a board using water-soluble solder flux without completely removing the flux residue from the board. The residue of such flux is soluble in water or water-soluble cleaning agents and the residue, especially the residues which contain active halogens, will negatively affect the performance and reliability of the product. (2) Using the product in any manner that will result in any shock or impact to the product. (3) Using the product in places where the product is exposed to water, chemicals, organic solvent, sunlight, dust, corrosive gasses, or other materials. (4) Using the product in places where it is exposed to static electricity or electromagnetic waves. (5) Applying ultrasonic cleaning without advance verification and confirmation that the product will not be affected by such a cleaning process which may damage the crystal. (6) Using the product under any other conditions that may negatively affect the performance and/or reliability of the product. (7) Using a power supply with ripple may cause of incorrect operation or degradation of phase noise characteristics, so please evaluate before use. It is recommended to keep power ripple below 200mVP-P. (8) Supply voltage should be increased monotonically. In addition, please do not power on at midpoint potential since that may cause malfunction or not output. When changing the VCC voltage during operation, change it more slowly than 1 μs / V. (9) Frequency aging is calculated from environmental tests results to estimate the amount of frequency variation over time. This does not guarantee the length of the product's life-cycle. Should any customer use the product in any manner contrary to the precautions and/or advice herein, such use shall be done at the customer’s own risk. N0: SG-3031CM_CMA_EN_rev1.0 p. 10
