PLL frequency synthesizer for tuners
BU2615S / BU2615FS
The BU2615 PLL frequency synthesizers work up through the FM band. Featuring low radiation noise, low power con-
sumption, and highly sensitive built-in RF amps, they support an IF count function.
FApplications
Tuners (Mini components, radio cassette players, radio
equipment, etc.)
FFeatures
1) Built-in high-speed prescaler can divide
130MHzVCO.
2) Basic oscillation of 75kHz keeps unnecessary radi-
ation 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 frequen-
cies.
6) Unlock detection
7) Seven output ports (open drain).
The BU2614, with three output ports, is also avail-
able.
8) Serial data input (CE, CK, DA)
FAbsolute maximum ratings (Ta = 25_C)
FRecommended operating power supply voltage
125
