156.25M Differential Series


The industry's smallest differential package, with jitter as low as 40 fs (maximum), excellent power supply noise and environmental interference suppression capabilities, an industry-standard package size as small as 2.0 x 1.6 mm, and wide temperature support up to 105°C; commonly available output drivers include LVPECL, LVDS, and HCSL.
High-frequency, low-jitter differential oscillators play a critical role in applications such as optical modules, Ethernet 400G/800G/1.6T, data centers, DWDM coherent optical transmission, network switches and gateways, system clocks, PCIE and automotive radar. With the tremendous growth of internet traffic, data centers are continuously increasing throughput, leading to higher demands for module transmission rates. To meet faster data rates, providing greater timing margins becomes increasingly important. At the same time, the miniaturization and high-density requirements of these modules also demand smaller differential oscillators.
