Small package high stability oscillator Sg2520egn/sg2520vgn, sg2520ehn/sg2520vhn
describe
With the implementation of 5G applications such as the Internet of Things and ADAS, data traffic continues to grow, and network infrastructure has become more important than ever before. IT suppliers have been rapidly building data centers and have a high demand for optical modules installed inside/within the data centers. This application requires a crystal oscillator with "small", "low jitter", and "high stability".
Smaller external dimensions (2520) solve the PCB layout limitations of QSFP-DD transceivers
The high-frequency fundamental oscillator is combined with our high-frequency crystal to achieve a low jitter of 19 fs type.
Internal integrated circuits allow a total tolerance of ± 20 x 10-6, including 105 ℃ operation and 10 years of aging
Recommended by major DSP manufacturers for PAM4/400ZR
characteristic
Output frequency range: 25mHz~500mHz
Size: 2.5 x 2.0 x 0.74 mm
Output: LV-PECL (SG2520EGN/SG2520EHN), LVDS (SG2520VGN/SG2520VHN)
Power supply voltage (VCC): 1.8 V (LVDS only)/2.5 V type/ 3.3 V type
