PLL frequency synthesizer for tuners

BU2614 / BU2614FS

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

radiation noise to a low level.

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

OFF 100µA).

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

following 7 frequencies: 25kHz, 12.5kHz, 6.25kHz,

3.125kHz, 5kHz, 3kHz, and 1kHz.

5) Counter for measurement of intermediate frequen-

cies.

6) Unlock detection.

7) Three output ports (open drain).

The BU2615, with seven output ports, is also avail-

able.

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