| Case | 20-VFQFN Exposed Pad |
The 2.25V to 3.6V supply range lets it run directly off a 2.5V or 3.3V rail — no extra LDO for the clock section.
The 20-VFQFN exposed pad package (5.00mm x 3.20mm body, 0.90mm height) requires a thermal via array under the pad for heat sinking and ground return — the datasheet's recommended land pattern should be followed for the LVDS signal integrity on the four outputs.
Buyers need to compare costs and budget for their BOM.
Immediate availability affects production timelines and rush orders.
Lead time impacts project scheduling and inventory planning.
Lifecycle status determines long-term availability and risk of redesign.
Engineers need drop-in replacements for second sourcing or stockouts.
Designers need to know if additional circuitry is needed for proper operation.
