Features

  • 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 BU2.

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.
