The BU2614 PLL frequency synthesizers work up through the FM band. Featuring low radiation noise, low power dis-

sipation, and highly sensitive built-in RF amps, they support an IF count function.

FApplications

Tuners (Mini components, radio cassette players, radio

equipment, etc.)

FFeatures

1) Built-in high-speed prescaler can divide 130MHzVCO.

2) Reference oscillation of 75kHz keeps unnecessary

3) Low current dissipation (during operation: 4mA, PLL

4) In addition to the standard FM and AM, also offers the
