PLL frequency synthesizer for tuners
BU2614 / BU2614FS
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.
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 frequencies. 6) Unlock detection.
