The PL611s-18-xxx is a general purpose frequency synthesizer and a member of the PicoPLL family, the world’s smallest programmable clocks. PL611s-18-xxx offers the versatility of using a single crystal (MHz) or reference clock input and producing up to two (kHz/MHz) system clocks, or a combination of reference and low frequency outputs. The PL611s-18-xxx is designed for low-power applications with very stringent space requirements and consumes, for example, ~1.0mA while producing two distinct outputs of 27MHz and 32kHz. The power down feature of PL611s-18-xxx, when activated, allows the IC to consume less than 5µA of power.The PL611s-18-xxx fits in a small DFN-6L or SOT23-6L package. Cascading of the PL611s-18-xxx with other programmable clocks allow generating system level clocking requirements, thereby reducing the overall system implementation cost.In addition, one programmable I/O pin can be configured as Output Enable (OE), Frequency switching (FSEL), Power Down (PDB) input, or CLK1 (CLK0, FREF, FREF/2) output.
