BU2615FS中文资料PLL frequency synthesizer for tuners数据手册ROHM规格书

描述 Description

The BU2615 PLL frequency synthesizers work up through the FM band. Featuring low radiation noise, low power consumption, and highly sensitive built-in RF amps, they support an IF count function.

特性 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.
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 available.
8) Serial data input (CE, CK, DA)Applications
  Tuners (Mini components, radio cassette players, radio equipment, etc.)
