PLL frequency synthesizer for tuners

BU2615S / BU2615FS

The BU2615 PLL frequency synthesizers work up through the FM band. Featuring low radiation noise, low power con-

sumption, 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.

5) Counter for measurement of intermediate frequen-

cies.

2) Basic oscillation of 75kHz keeps unnecessary radi-

ation noise to a low level.

6) Unlock detection

7) Seven output ports (open drain).

The BU2614, with three output ports, is also avail-

able.

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

OFF: 100µA)

4) InadditiontothestandardFMandAM, alsooffersthe

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

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

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