8T49N488A-000ASGI

Overview

The 8T49N488A-000ASGI is a quad PLL universal frequency translator utilizing FemtoClock NG technology. It integrates low-phase noise frequency translation, jitter attenuation, and alarm monitoring functions for networking applications. The device features four independent PLLs with programmable outputs supporting LVPECL or LVDS signaling. Input frequencies range from 8kHz to 710MHz, while output frequencies are programmable from 0.98MHz up to 1300MHz. It operates on a full 2.5V ± 5% supply within an ambient temperature range of -40°C to 85°C.
