The BU2618FV is a low current dissipation PLL frequency synthesizer designed for use in FM multiplex radio receiver and FM pager receiver. Featuring very small package and built-in prescaler that can operate at up to 130MHz.

Features
1) Built-in high-speed prescaler can divide 130 MHzVCO.
2) Low current dissipation (during operation: 1.5mA, PLL OFF: 200µA Typ.)
3) Seven standard frequencies: 25kHz, 12.5kHz, 6.25kHz, 10kHz, 9kHz, 5kHz, and 1kHz.
4) Counter for intermediate frequency detection.
5) Unlock detection circuit.
6) Four output ports.
7) Serial data input (CE, CK, DA)

Applications
    FM multiplex radio receivers, pagers, radios, and other signal generators
