> (fo = 26 MHz, 100 kHz offset) **Description** 

## **Applications** 

• GNSS 

- RF 

- Wireless communication devices 

- LTE, WiMAX, Wi-Fi, W-LAN 

- IoT etc.. 

TG2016SMN / TG2520SMN are high stability and low phase noise TCXOs using an Epson-developed and fabricated IC and MHz fundamental crystal . 

The phase noise is the lowest of Epson’s compact TCXO products lineup, making it an ideal reference clock for GNSS and other wireless communication devices.

Impossible to measure both frequency and wave form at the same time. 

(In case of using oscilloscope's amplifier output, possible to measure both at the same time.) 

(2) Load_C includes probe capacitance.

## [ 13 ] 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 us 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 the deteriorating performance of the product, we strongly recommend that you DO NOT use the product under ANY of the following conditions: 

- (1)  Do not expose this product to excessive mechanical shock or vi 

- (2)  This product can be damaged by mechanical shock during the soldering process depending on the equipment used, process conditions, and any impact forces experienced. Always follow appropriate procedures, particularly when changing the assembly process in anyway and be sure to follow applicable process qualification standards before starting production. 

- (3)  These devices are sensitive to ESD, please use appropriate precautions during handling, assembly, test, shipment, and installation. 

- (4)  This product contains semiconductor content that should not be exposed to electromagnetic waves. 

- (5)  The use of ultrasonic technology for cleaning, bonding, etc. can damage the Xtal unit inside this product. Please carefully check for this consideration before using ultrasonic equipment for volume production with this product. 

- (6)  Noise and ripple on the power supply may have undesirable affects on operation and cause degradation 

- of phase noise characteristics. Evaluate the operation of this device with appropriate power supplies carefully before use. 

- (7)  When applying power, ensure that the supply voltage increases monotonically for proper operation. On power down, do not reapply power until the supplies, bypass capacitors, and any bulk capacitors are completely discharged since that may cause the unit to malfunction. 

- (8)  Aging specifications are estimated from environmental reliability tests and expected frequency variation over time. They do not provide a guarantee of aging over the product lifecycle. 

- (9)  The metal cap on top of the device is directly connected to the GND terminal (pin #2). Take necessary 

- precautions to prevent any conductor not at ground potential from contacting the cap as that could cause a short circuit t 

- (10)Do not route any signal lines, supply voltage lines, or GND lines underneath the area where the oscillators are mounted including any internal layers and on the opposite side of the PCB. 

- To avoid any issues due to interference of other signal lines, please take care not to place signal lines near the product as this may have an adverse affect on the performance of the product. 

- (11)A bypass capacitor of the recommended value(s) must be connected between the VCC and GND terminals of the product. Whenever possible, mount the capacitor(s) on the same side of the PCB and as close to the product as possible to keep the routing traces short. 

- (12)Power supply connections to Vcc and GND pins should be routed as thick as possible while keeping the high frequency impedance low in order to get the best performance. 

- (13) The use of a filter or similar element in series with the power supply connections to protect from electromagnetic radiation noise may increase the high frequency impedance of the power supply line and may cause the oscillator to not operate properly. Please verify the design to ensure sufficient operational margin prior to use. 

- (14) Keep PCB routing from the output terminal(s) to the load as short as possible for best performance. 

- (15) Do not short the output to GND as that will damage the product. Always use with an appropriate load resistor connected. 

- (16) Product failures during the warranty period only apply when the product is used according to the recommended operating conditions described in the specifications. Products that have been opened for analysis or damaged will not be covered. It is recommended to store and use in normal temperature and humidity environments described in the specifications to ensure frequency accuracy and prevent moisture condensation. If the product is stored for more than one year, please confirm the pin solderability prior to use. 

- (17) If the oscillation circuit is exposed to condensation, the frequency may change or oscillation may stop. Do not use in any conditions where condensation occurs. 

- (18) Do not store or use the product in an environment where it can be exposed to chemical substances that are corrosive to metal or plastics such as salt water, organic solvents, chemical gasses, etc. 

- Do not use the product when it is exposed to sunlight, dust, corrosive gasses, or other materials for long periods of time. 

- (19) When using water-soluble solder flux make sure to completely remove the flux residue after soldering. Pay particular attention when the residues contain active halogens which will negatively affect the product and its performance. 

- (20) Do not touch the surface of the IC with tweezers or other hard tools. 

- (21) Do not use adhesives with this product as this will cause the oscillation to stop if the IC is damaged by adhesive. This product uses an underfill material on the bottom side of package where adhesive near the bottom side may cause the TCXO to be damaged by thermal expansion.

## FCS eae **PROMOTION OF ENVIRONMENTAL MANAGEMENT SYSTEM CONFORMING TO INTERNATIONAL STANDARDS** 

At Seiko Epson, all environmental initiatives operate under the Plan-Do-Check-Action (PDCA) cycle designed to achieve continuous improvements. The environmental management system (EMS) operates under the ISO 14001 environmental management standard. All of our major manufacturing and non-manufacturing sites, in Japan and overseas, completed the acquisition of ISO 14001 certification. 020200eee **WORKING FOR HIGH QUALITY** 

In order provide high quality and reliable products and services than meet customer needs, Seiko Epson made early efforts towards obtaining ISO9000 series certification and has acquired ISO9001 for all business establishments in Japan and abroad. We have also acquired IATF 16949 certification that is requested strongly by major manufacturers as standard. 

ISO 14000 is an international standard for environmental management that was established by the International Standards Organization in 1996 against the background of growing concern regarding global warming, destruction of the ozone layer, and global deforestation. 

IATF 16949 is the international standard that added the sector-specific supplemental requirements for automotive industry based on ISO9001.
