Introduction
The L12M3.1L LA chassis is a digital chassis using a Mediatek
chipset. It covers screen sizes of 32" to 55".
Main key components are the Mediatek MT5396 integrated
“System On Chip” (SoC) that supports multimedia video/audio
input.
System SoC is based on MT5396:
•
NAND Flash – 512 Mbyte, Hynix.
•
DDR 1.33 GHz– 512 + 256 Mbyte, Hynix.
Tuner/Frontend configuration:
•
Sony Silicon In Can Tuner (SUT-RA214Z).
•
Sony Digital Demodulator (CXD2828).
•
Analog demodulator embedded in MT5396.
Audio configuration:
•
Texas Instruments Audio Class-D Amplifier
(TAS5731PHP).
•
Texas Instruments Headphone Amplifier
(TPA6111A2DGN).
