AD9531

3-Channel Clock Generator, 24 Outputs

Product Details

The AD9531 provides a multioutput clock generator function and three on-chip phase-locked loop (PLL) cores with SPI programmable output frequencies and formats.

PLL1 provides two reference inputs and 10 outputs and includes four user selectable loop configurations. The PLL has a fully integrated loop filter requiring only a single external capacitor (or a series RC network). PLL1 provides a wide range of output frequencies up to 400 MHz and is capable of operating with an external voltage controlled crystal oscillator (VCXO) and loop filter, instead of the integrated voltage controlled oscillator (VCO) and loop filter.

PLL2 is an integer-N PLL providing a single reference input and 12 outputs. PLL2 synthesizes output frequencies up to 400 MHz from the REF2_x source and synchronizes the output clocks to the input reference.

PLL3 provides a single reference input and two outputs. PLL3 synthesizes output frequencies up to 400 MHz from the REF3_x source and synchronizes the output clocks to input reference.

The AD9531 is available in an 88-lead LFCSP and is specified over the −40°C to +85°C operating temperature range.

Throughout this data sheet, multifunction pins, such as LOR/M4, are referred to either by the entire pin name or by a single function of the pin (for example, LOR, when only that function is relevant). In other cases, the text and figures of this data sheet contain references to a channel rather than a pin. For example, REF_A refers to the REF_A channel rather than the REF_AP and REF_AN pins. Likewise, OUT3_1 refers to Channel 1 of PLL3 rather than the OUT3_1P and OUT3_1N pins. Additionally, an abbreviated notation for a pin pair replaces an explicit reference to a each pin (for example, REF_Ax signifies the REF_AN and REF_AP pins.).
