Features
• Single Supply . . . . . . . . . . . . . . . . . . . . . . . . . 2.7V to 3.3V
The ISL3084 is a 5GHz SiGe
monolithic VCO circuit designed to
simplify and reduce the cost and size
of miniature wireless transceivers.
• Frequency . . . . . . . . . . . . . . . . . . . . . . . . . 4.9GHz typical
• Fully Integrated/No External Varactors or Resonators
Required
A fully integrated VCO requiring no external elements such
as inductors and varactors greatly simplifies low cost local
oscillator synthesized applications.
• Isolation Output Buffer/Reduced Load Pulling
• Differential Design/Reduced Spurs
• Digitally Controlled Power Down Mode
• QFN Package:
Included in this differential design is a low-power standby
function and a stable process and temperature biasing
operation.
- Compliant to JEDEC PUB95 MO-220 QFN - Quad Flat
No Leads - Package Outline
The ISL3084 is housed in a 16 lead QFN package
well-suited for PCMCIA and miniPCI board applications.
- Near Chip Scale Package footprint, which improves
PCB efficiency and has a thinner profile

NOTES:
1. Dimensioning and tolerancing conform to ASME Y14.5-1994.
2. N is the number of terminals.
3. Nd and Ne refer to the number of terminals on each D and E.
4. All dimensions are in millimeters. Angles are in degrees.
5. Dimension b applies to the metallized terminal and is measured
between 0.15mm and 0.30mm from the terminal tip.
6. The configuration of the pin #1 identifier is optional, but must be
located within the zone indicated. The pin #1 identifier may be
either a mold or mark feature.
7. Dimensions D2 and E2 are for the exposed pads which provide
improved electrical and thermal performance.
8. Nominal dimensionsare provided toassistwith PCBLandPattern
Design efforts, see Intersil Technical Brief TB389.
9. Features and dimensions A2, A3, D1, E1, P & θ are present when
Anvil singulation method is used and not present for saw
singulation.
10. Depending on the method of lead termination at the edge of the
package, a maximum 0.15mm pull back (L1) maybe present. L
minus L1 to be equal to or greater than 0.3mm.
