ADI’s AD9530 / AD9531 are single- and multi-output clock generators. The AD9530 is a fully integrated PLL and distribution supporting, clock cleanup, and frequency translation device. The AD9530 features an internal 5.11 GHz to 5.4 GHz voltage controlled oscillator (VCO). All four outputs are individually divided down from the internal VCO using two high speed VCO dividers and four individual 8-bit channel dividers.

The AD9531 provides a multi-output clock generator function and three on-chip PLL cores with serial peripheral interface (SPI) programmable output frequencies and formats. The PLL1 is a fractional-N/integer with and optional external VCXO. The PLL2 is an integer-N with input format of differential/single-ended/crystal. The PLL3 is an integer-N with a frequency range of 9.5 MHz to 100 MHz.

The AD9530 comes in a small 7 mm x 7 mm 48-LFCSP package and the AD9531 comes in a 12 mm x 12 mm 88-LFCSP package. Both have an operating temperature range of -40°C to +85°C.
