CCB is a SANYO’s original bus format and all the
bus addresses are controlled by SANYO.

The LV25300M is a tuning system that supports the LC75030W (SANYO audio DSP) that allows the creation of standard
tuner modules. Various setting changes can be performed with the software of the control microcontroller according to the
intended application, making the LV25300M ideal for combined use with the LC75030W. Small tuner modules can be
developed with a smaller number of parts compared to conventional tuners and at a lower total cost. Since the LV25300M
has a serial bus (CCB SANYO bus), the number of communication lines with the microcontroller is reduced by 4 and line
routing problems during set production can be avoided, making a smaller board size possible. AM/FM wave demodulation
is done through digital processing by outputting the IF signal (450 kHz) of the LV25300M to the LC75030W.
Since the LC75030W has a function to change the IF selectivity according to the level of adjacent interference, just two

10.7 MHz ceramic filters suffice to achieve both high sound quality and adjacent interference, which used to be difficult until
now because these are somewhat mutually exclusive characteristics. Moreover, the LV25300M comes with an antenna
switching diversity function that switches two antennas in response to various electric field changes during operation, a
malfunction prevention circuit that operates through antenna switching frequency detection, and a weak electric field
detection and antenna fixing circuit that uses S meter voltage, making stable reception possible.
Optimum tuner reception is possible by outputting the voltages of the LV25300M' S meter output and the AM/FM IF outputs
to a DSP and judging the radio wave status in real time, and performance combinations and specification differentiation can
be performed by software.

Super System-on-Chip Digital Servo IC with On-Chip RF SystemSuper System-on-Chip Digital Servo IC with On-Chip RF System

: Use of conditional products requires
consultation with a SANYO representative
prior to the use of the device.

The LC78648NEH integrates, on a single chip, the RF signal processing, servo control, EFM signal processing,
and audio signal processing required for audio CD playback.
This single IC can perform all the CD data signal processing required to convert the signal read from the disc to
an analog audio signal. A basic CD player system can be implemented with just three ICs
(this IC, a microcontroller, and a driver IC) and a minimal number of external components.

WMA DecoderWMA Decoder

The LC78685V is a WMA decoder IC. This IC is implemented using a dedicated hard wired circuit structure
to achieve low power consumption. Various format (CD-DA, MP3, and WMA) audio data recorded on CDs can
be played back by adding this IC to a system structure consisting of a CD player signal-processing IC and a
CD-MP3 IC (such as the LC78684).
The LC78685V makes it easy to implement CD players that provide multiformat decoding functions.

■ A 5 Mbps or 7.5 Mbps automotive LAN can be implemented by combining the LA2351M with an automotive LAN
protocol IC (ARCNET controller TMC20040C series device).

■ The low-pass filter required for adjustment is built in

■ Supports low-noise data communication

■ Package: MFP30SD (375 mil)
