BU2615S / BU2615FS (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, P3, P4, P5, P6 1: Open drain output ON (P5 is LO) 0: Op

Features

1) Built-in high-speed prescaler can divide 130MHzVCO. 2) Basic 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. FAbsolute maximum ratings (Ta = 25_C) 5) Counter for measurement of intermediate frequencies. 6) Unlock detection 7) Seven output ports (open drain). The BU2.
