PL613-01 - Micrel

PL613-01 8-Output Clock

The PL613-01 is an advanced triple PLL design based on PicoPLLTM, world’s smallest programmable clock, technology. This advanced technology allows the 8 output PL613-01 to fit in to a small 3mmx3mm QFN package or (T)SSOP for high performance, lowpower, low-cost applications. Besides its small form factor and 8 outputs that can reduce overall system costs, th.

of these products is mentioned in the following paragraphs. PLL Programming The three PLLs in PL613-01 are fully programmable. Each PLL is equipped with an 8-bit input frequency divider (R-Counter) and an 11-bit VCO frequency feedback loop (M-Counter) divider. The three PLL outputs are transferred to five 5-bit post VCO, Odd/Even dividers (P-Counter), as shown in the above diagrams. In addition, there are three optional (÷1, ÷2, ÷4 or ÷8) post P-Counter dividers, that can further divide the VCO frequency. In general, the PLL output frequency is determined by the following formula: FOUT = (FRE.
