PLL frequency synthesizer for tuners
BU2616F
BU2616F PLL frequency synthesizers work up through the FM band. Featuring low power dissipation and highly sensitive built-in RF amps, they detect intermediate frequencies. FApplications Tuners (Mini components, radio cassette players, radio equipment, etc.) FFeatures 1) Built-in high-speed prescaler can divide 130MHzVCO. 2) Low current dissipation (during operation: 6mA PLL OFF: 1mA) 3) In addition to the standard FM and AM, also offers the following 7 frequencies: 25kHz, 12.5kHz, 6.25kHz, 10kHz, 9kHz, 5kHz, and 1kHz. 4) SD (station detector) input circuit. FAbsolute maximum ratings (Ta = 25_C)
5) 6) 7) 8)
Intermediate frequency detection circuit Charge pump output control circuit Four output ports (Nch open drain).
