CMOS LSI
FM multiple tuner IC
http://onsemi.com
Overview
LC01707PLF is a vehicle-mounted FM multiple tuner IC with FM-FE, IF, IF-Filter, PLL, FM-DEMO and LPF incorporated. An FM multiple tuner can be developed with this one chip. It makes up a small-sized FM multiple tuners which can be mounted on PND.
Functions
• It is the FM tuner IC exclusively for the FM multiple.
• LNA is incorporated
• Image reduction complex BPF is incorporated
• Wide / Narrow Band RF AGC is incorporated
• Narrow Band IF AGC is incorporated
• Image rejection is adopted
• DLL detection method is adopted for the FM detection circuit, and it is not necessary to adjust.
• LPF for the carrier removal is incorporated.
• IC requires fewer external components.
• It is a BUS control tuner IC which can be controlled by controlled by I2C BUS.

* Culprits oscillation circuit is used in this IC as a crystal oscillation circuit. Caution is required for layout of the board because oscillation between pin25 and power source and GND line. * The margin of crystal oscillation changes due to the combination of the IC, a crystal oscillator and a board layout. This independent IC does not quarantine the oscillation operation. * This IC uses the signal of FM band frequency (VCO divided into 1/4) which leaks into ANT pin. If the VCO leakage affects the performance of the system, make sure to connect an isolator on ANT pin path.
