IoT Devices / EMI reduction

Epson devices support IoT penetration.
- Connecting a decentralized global world
 With the expansion of IoT usage, various radio waves are mixed in the wireless signal paths, and the
 risk of system malfunction and failure due to EMI (radiated noise) is increasing.
 As a solution to EMI caused by oscillators, we provide crystal oscillators (SPXO) that can reduce EMI,
 contributing to the realization of a connected world through IoT.


Value proposition

IoT Devices / EMI reduction
   Epson's Spread Spectrum Programmable SPXO Summary :

- We provide SPXO that enables EMI reduction by spread spectrum technology
 Value proposition :
 - Various spread spectrum specifications can be selected based on the customer's
  design requirements.
 - Programmable function enables fast response to frequency changes*1
 - Can be used to replace general oscillators without changing the board layout*2  

Spread Spectrum

*1: Arbitrary frequency can be programmed up to 6 decimal point accuracy. (Once programming is done, overwriting is not
  possible) In case of general oscillators, new crystal designs may be needed for every new frequency required.
*2: Adopts the same footprint as our general oscillators line up of sizes 2.5 x 2.0, 3.2 x 2.5, 5.0 x 3.2, 7.0 x 5.0 mm
