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.

5) Unlock detection circuit

6) Five output ports (open drain)

7) SD input port

2) Low current dissipation (during operation: 6.0mA,

PLL OFF: 300µA Typ.)

8) Two charge pump outputs

9) Serial data input (CE, CK, DA)

10) Control of phase comparison output

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)

FRecommended operating conditions (Ta = 25_C)
