Overview

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.

Key Features

1) Built-in high-speed prescaler can divide 130MHzVCO. 2) Low current dissipation (during operation: 6.0mA, PLL OFF: 300µA Typ. ) 3) Seven standard frequencies: 50kHz, 25kHz, 12.5kHz, 10kHz, 9kHz, 5kHz, and 1kHz. 4) Two counters for intermediate frequency detection FAbsolute maximum ratings (Ta = 25_C) 5) 6) 7) 8) 9) 10) Unlock detection circuit Five output ports (open drain) SD input port Two charge pump outputs Serial data input (CE, CK, DA) Control of phase comparison output FRecommended op.
