Si5330 Clock Buffers/Level Translators

Skyworks Solutions Inc. Si5330 Clock Buffers/Level Translators are low-jitter, low-skew fanout buffers designed for high-performance PCB clock distribution applications. These Si5330 buffers and translators support single-ended or differential input clock signals. The devices produce four differential/eight single-ended, low-jitter output clocks from a single input clock allowing them to function as clock level translators. The output driver voltage of these devices is 1.5, 1.8V, 2.5V, or 3.3V and is independent of the core supply of 1.8V, 2.5V, or 3.3V. These buffers/translators consume low power with just 10mA typical core current. These clock buffers/level translators have 150fs RMS of additive jitter and 100ps of output-output skew. The typical applications include high-speed clock distribution, ethernet switches and routers, SONET/SDH, fiber channels, and telecom line cards.
