LV25500PQA: FM Multiplex Broadcasting Receive Tuner
LV25500PLF is in-vehicle FM multiplex broadcasting receive only tuner IC that makes FM tuner, PLL, and the RDS demodulator single-chip. ON Semiconductor’s unique technology enables to reduce a large number of external components for high frequency like coils, ceramic filters and varicaps which were required for conventional tuner IC. Small FM multiple tuner that can be installed also in PND etc. including AVN can be composed.
应用功能框图
特性- No need for adjustment work.
- The AF search processing on the main tuner side is unnecessary according to using with the main tuner together.
- The high sensitivity reception and the high strong input tolerance are united by LNA built into equipped with the WIDE-AGC function.
- The third and fifth high harmonic rejection type mixers of a local oscillation are adopted.
- The switch of UPPER/LOWER of a local oscillation and IF-BPF of injection is possible when the image signal is detected.
- The complex BPF of the image attenuation type is built into.
- IF-BPF is made built-in by LOW-IF frequency (IF = 575 kHz) adoption.
- Dynamic range of S meter is wide.
- S meter tuning-system is adopted.
- The DLL demodulation method is adopted for FM demodulation circuit.
- LPF for the carrier removal is built into.
- S meter level, the adjacent obstruction level, and the multipath can be detected and read by way of I2C BUS.
- BPF (57 kHz) for the BPSK detection is built into.
- It becomes easy to miniaturize the tuner set with built-in the RDS demodulator.
- 36.8MHz is adopted for the crystal oscillation frequency.
- The number of external parts is little.
