Tuner System IC with Built-in PLL
for Car Audio Applications
Overview
The LA17000M is an all-in-one car tuner IC that incorpo-
rates 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
