The 853S9252I is a 2.5V/3.3V ECL/LVPECL fanout buffer designed for high-speed, low phase-noise wireless infrastructure applications. The device fanouts a differential input signal to two ECL/LVPECL outputs. Optimized for low additive phase-noise, sub-100ps output rise and fall times, low output skew and high-frequencies, the 853S9252I is an effective solution for high-performance clock and data distribution applications, for instance driving the reference clock inputs of ADC/DAC circuits. Internal input termination, a bias voltage output (VREF) for AC-coupling and small packaging (3.0mm x 3.0mm 16-lead VFQFN) supports space-efficient board designs. The 853S9252I operates from a full 2.5V or 3.3V power supply and supports the industrial temperature range of -40°C to 85°C. The extended temperature range also supports wireless infrastructure, tele-communication and networking end equipment requirements.
