PLL frequency synthesizer for tuners
BU2616F
BU2616F PLL frequency synthesizers work up through the FM band.
Featuring low power dissipation and highly sensitive built-in RF amps, they detect intermediate frequencies.
FApplications
Tuners (Mini components, radio cassette players, radio
equipment, etc.)
FFeatures
1) Built-in high-speed prescaler can divide 130MHzVCO.
2) Low current dissipation (during operation: 6mA PLL
OFF: 1mA)
3) In addition to the standard FM and AM, also offers the
following 7 frequencies: 25kHz, 12.5kHz, 6.25kHz,
10kHz, 9kHz, 5kHz, and 1kHz.
4) SD (station detector) input circuit.
