LA17000M

• PLL on chip
• ADC (6 bits, 1 channel)
• IF counter and I/O port on chip permit simplification of the interface.
• Supports AM double conversion.
• Enhanced noise countermeasures
• Excellent tri-signal characteristics
• Improved medium and weak electric field NC characteristics
• Improved separation characteristics
• Anti-birdie filter on chip (analog/digital output)
• Multipath sensor output (analog/digital output)
• Cost-saving features
• AM double conversion (Up conversion method)
• Enhanced FM-IF circuit (When there is interference from adjacent frequencies,the software handles switching of the CF between wide and narrow automatically.)
• Because deviations in IF gain are only 1/3 that of earlier devices, adjustment is simplified when this IC is incorporated into a set; this IC also includes a shifter pin for VSM adjustment.
• Suited for smaller devices
• Permits high-frequency signal line processing in a tuner pack.
• Easily conformes to FCC standards

The LA17000M is an all-in-one car tuner IC that incorporates a PLL frequency synthesizer and all functions of an AM/FM tuner in a single chip. By combining two chips, a PLL (LC72144 equivalent) and an FM tuner IC (LA1781M equivalent) into a single chip (*PLL + AM (up conversion) + FMFE + IF + NC + MCP + MRC), and as a result of optimal chip partitioning, the LA17000M improves the performance of car tuner systems, eliminates adjustments, and provides high reliability, all at a lower cost.
