The BU2614 PLL frequency synthesizers work up through the FM band. Featuring low radiation noise, low power dissipation, and highly sensitive built-in RF amps, they support an IF count function.

Features

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 available.

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

Applications

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