Epson E Series SPXOs

Epson E series SPXOs provide ultra-low jitter and tight stability in a small package and are suitable for networking applications with very high data rates. The series deliver swide-open eye diagrams for high-speed (10, 25, 40, 100, 200, and 400Gbps) optical and electrical interfaces. To achieve ultra-low jitter, 50fs rms jitter at 156.25MHz, Epson’s E series SPXOs use a HFF (high-frequency fundamental) crystal and a unique low-noise oscillator IC. Their excellent jitter performance enables superior eye diagrams for high-speed electrical and optical interfaces. To ensure consistent performance for complex designs, Epson E series SPXOs include an LDO (low drop-out) voltage regulator to protect the clock from power supply noise.
