Description

BU2614 / BU2614FS 118 Audio ICs FElectrical characteristics (unless otherwise noted, Ta = 25_C, VDD1 = VDD2 = 5.0V) BU2614 / BU2614FS 119 Audio ICs FInput data format BU2614 / BU2614FS 120 Audio ICs FExplanation of the data (1) Division data: For D0 through D15 (When S = 1, use D4 through D15.) BU2614 / BU2614FS (2) (3) (4) CT: Frequency measurement beginning data 1: Beginning of measurement 0: Internal counter is reset, IFIN is pulldown.Output port control data: P0, P1, P2 1: Op

Features

1) Built-in high-speed prescaler can divide 130MHzVCO. 2) Reference oscillation of 75kHz keeps unnecessary radiation noise to a low level. 3) Low current dissipation (during operation: 4mA, PLL OFF 100µA). 4) In addition to the standard FM and AM, also offers the following 7 frequencies: 25kHz, 12.5kHz, 6.25kHz, 3.125kHz, 5kHz, 3kHz, and 1kHz. 5) Counter for measurement of intermediate frequencies. 6) Unlock detection. 7) Three output ports (open drain). The BU2615, with seven output ports, is.
