LV23000M
Single-Chip Tuner IC for Radio/Cassette Players
Overview
The LV23000M is a single-chip tuner IC for radio/cassette
players that provides FM, AM, MPX, and PLL circuits. It
allows the tuner PCB to be simplified significantly.
Functions
• AM tuner
• FM tuner
• Multiplex stereo decoder
• PLL frequency synthesizer
Features
• Tuner circuit includes built-in PLL for easy end product
design.
• Supports FCC standards
• Built-in adjustment-free multiplex VCO
• AM low-cut control
• Provides the transistor required to implement an active
low-pass filter.

• In this state, the programmable divider block and the IF counter block are stopped, FMIN,
AMIN, and IFIN are pulled down (to ground), and the charge pump goes to the high-
impedance state.
IF counter control data
• Measurement start data for the IF counter
CTE = 1: Start the count.
= 0: Reset the counter.
• Determines the measurement time for the general-purpose counter.
