■Notes:
In order to achieve optimum jitter performance, the 0.1 μF capacitor between VCC and GND should be placed. It is also
recommended that the capacitors are placed on the device side of the PCB, as close to the device as possible and connected
together with short wiring pattern.

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.
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 ISO/TS
16949 certification that is requested strongly by major automotive
manufacturers as standard.
►Explanation of the mark that are using it for the catalog
