Overview

Audio ICs PLL frequency synthesizer for tuners BU2615S / BU2615FS The BU2615 PLL frequency synthesizers work up through the FM band.
Featuring low radiation noise, low power consumption, 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) Basic 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.
FAbsolute maximum ratings (Ta = 25_C) 5) Counter for measurement of intermediate frequencies.
6) Unlock detection 7) Seven output ports (open drain).
The BU2614, with three output ports, is also available.
8) Serial data input (CE, CK, DA) FRecommended operating power supply voltage 125 Audio IC...
