No Preview Available ! Audio ICs 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).
