The LA17000M is a car audio system tuner IC that integrates both a PLL frequency synthesizer and all AM/FM
functions on a single chip. The LA17000M combines the functions of two ICs, a PLL IC (such as the LC72144)
and an FM tuner IC (such as the LA1781M) on a single chip that provides PLL, AM (upconversion), FM FE, FM IF,
NC, MCP, and MRC functions. The LA17000M achieves increased performance, adjustment-free manufacturing,
and high reliability at low cost in car tuner systems by providing an optimal functional allocation in the IC.
Car Audio Tuner IC with Built-in PLL CircuitCar Audio Tuner IC with Built-in PLL Circuit
■ Built-in PLL
◆
A/D converter (6 bits, 1 channel)
◆
IF counter and I/O ports for simplified interface
design
◆
Supports AM double conversion reception
■ Strengthened noise reduction
◆
Superlative three-signal characteristics
◆
Improved weak and medium-field NC
characteristics
◆
Improved separation characteristics
◆
Built-in anti-birdie filter (analog and digital outputs)
◆
Anti-multipath sensor outputs
(analog and digital outputs)
■ Support for lower costs
◆
AM double conversion (upconversion)
◆
Improved FM IF circuit (automatic wide/narrow
ceramic filter switching under adjacent channel
interference conditions)
◆
IF gain sample-to-sample variations reduced to 1/3
that in previous devices. This simplifies end product
adjustment during manufacture. Furthermore,
a shifter pin is provided for VSM adjustment.
■ Supports end product miniaturization
◆
High-frequency signal lines can be handled within
the tuner pack.
◆
Easily meets FCC requirements
■ Package: QFP80 (14 14 mm)

The LC75410E/W is an electronic volume and tone control IC that implements a rich set of audio control
functions with a minimal number of external components. Functions include volume, balance, fader,
bass/midrange/treble, and loudness controls, as well as input selection/switching functions and an input
gain control.

Overview Overview

Functions
Features
:CCB is SANYO's original bus format.
All bus addresses are managed by
SANYO for this format.
■ On-chip buffer amplifiers reduce the number of external components
■ Internal switches are implemented in a silicon gate CMOS process that minimizes the noise generated when switching.
This results in low noise even when switching in the no-signal state.
■ Zero-cross switching circuits used for low noise even when input signals are present
■ Built-in VDD/2 reference voltage generation circuit
■ All functions are controlled using serial data (CCB)
■ Packages: LC75410E: QIP64E (14 14 mm)
LC75410W: SQFP64 (10 10 mm)
■ Volume control: A total of 161 positions from 0 dB to -79.5 dB in 0.5 dB steps and -∞ dB.
A balance function can be implemented by controlling the left and right channel volume controls separately.
■ Fader control: The rear or front outputs can be attenuated by one of 16 levels
(A total of 16 settings with attenuations of 0 to -2 dB in 1dB steps, -2 to -20 dB in 2 dB steps, -20 to -30 dB in 10 dB steps,
and -45, -60, and -∞ dB settings.)
■ Bass/midrange/treble controls: Each band can be controlled in 1 dB steps from 0 dB to ±6 dB, and in 2 dB steps from
±8 dB to ±12 dB
■ Input gain control: The input signal can be amplified by 0 to +18.75 dB in 1.25 dB steps
■ Input switching: One of five input systems (left and right channels) can be selected
(Four of the input systems are single-ended inputs, one uses differential inputs.)
■ Loudness control: The -32 dB position of the 2 dB step volume control ladder resistor can be tapped and a loudness
function implemented with external capacitor and resistor components
