PLL frequency synthesizer for tuners
BU2618FV
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.
FApplications
FM multiplex radio receivers, pagers, radios, and other
signal generators
FFeatures
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)
FAbsolute maximum ratings (Ta = 25_C)
FRecommended operating conditions (Ta = 25_C)
