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
