3. Ordering Information

Specific device configurations are programmed into the Si590/591 at time of shipment. Configurations can be

specified using the Part Number Configuration chart below. Silicon Laboratories provides a web browser-based

tool and for further ordering instructions. The Si590 and Si591 XO series are supplied in an industry-standard,

RoHS compliant, 6-pad, 5 x 7 mm package. The Si591 Series supports an alternate OE pinout (pin #1) for

LVPECL, LVDS, and CML output formats. See Tables 8 and 9 for the pinout differences between the Si590 and

Si591 series.

Frequency (e.g., 148M352 is 148.352 MHz)

Available frequency range is 10 to 525 MHz. The position of “M” shifts

to denote higher or lower frequencies. If the frequency of interest

requires greater than 6 digit resolution, a six digit code will be

assigned for the specific frequency.
