1 / 9 page 161 Audio ICs PLL frequency synthesizer for tuners BU2624AF The BU2624AF is a PLL frequency synthesizer IC designed for use in car stereos, high-fidelity audio systems, and CD radio cassettes. Featuring low current dissipation, low superfluous radiation, two frequency measurement counter systems, and two phase comparison outputs, this chip is ideal for high-performance multi-band systems. FApplications Car stereos, high-fidelity audio systems, radio cassettes, receivers, and other frequency generating devices FFeatures 1) Built-in high-speed prescaler can divide 130MHzVCO. 2) Low current dissipation (during operation: 6.0mA, PLL OFF: 300 µA Typ.) 3) Seven standard frequencies: 50kHz, 25kHz, 12.5kHz, 10kHz, 9kHz, 5kHz, and 1kHz. 4) Two counters for intermediate frequency detection 5) Unlock detection circuit 6) Five output ports (open drain) 7) SD input port 8) Two charge pump outputs 9) Serial data input (CE, CK, DA) 10) Control of phase comparison output FAbsolute maximum ratings (Ta = 25_C) FRecommended operating conditions (Ta = 25_C) |
