General Description

s 120 Audio ICs FElectrical characteristics (unless otherwise noted, Ta = 25_C, VDD1 = VDD2 = 5V) BU2616F FInput data format 121 Audio ICs FInput data format Explanation of the data (1) Division data: For D0 through D15 (When S = 0, use D4 through D15.) BU2616F Example: S = 0, SW = 0 When divide ratio = 1000, the actual set value is 500 since it passes through 1 / 2 the circuit.

This translates to 1F4 (H) in HEX notation, and to (MSB) 0000 0001 1111 0100 (LSB) in binary notation.

This data is used from LSB to D0 through D15.

Overview

Audio ICs 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.

Key Features

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). Serial data input (CE, CK, DA) FRecomme.
