Overview
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.

Features
• 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
