STCD1020, STCD1030, STCD1040 are low-power, low-phase-noise multi-channel clock distribution circuits. They are available in 2, 3 or 4-output versions with single-ended sine or square-wave clock input and output. Each output has an independent clock enable, reducing clock source fanout. The input does not require AC coupling capacitors, making them ideal for multi-mode RF clock references and baseband peripherals clock references.
