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.

Applications
Tuners (Mini components, radio cassette players, radio
equipment, etc.)

Features

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.

5) Intermediate frequency detection circuit

6) Charge pump output control circuit

7) Four output ports (Nch open drain).

8) Serial data input (CE, CK, DA)
