Страница: 36 / 95

An auto refresh mode is provided along with a power-saving power-down mode. All inputs are
compatible with the Industry Standard for SSTL_2. All outputs are SSTL_2, Class II compatible.
Note: The functionality described and the timing specifications included in this data sheet are for the
DLL Enabled mode of operation.
I501 Tuner
The Antenna receive the TV signal and modulate it to the CVBS signal and ATSC signal which can be
recognized By the decoder and MTS audio signal output to the sound multiplexing decoder portion of
IC MSD2248AL
I601 YDA148 AUDIO AMP
YDA148 (D-510) is a high-efficiency digital audio power amplifier IC with the maximum output of
15W × 2ch.
YDA148 has a “Pure Pulse Direct Speaker Drive Circuit” that directly drives speakers while reducing
distortion of pulse output signal and reducing noise on the signal, which realizes the highest standard
low distortion rate characteristics and low noise characteristics among digital amplifier ICs in the same
class.
In addition, supporting filterless design allows circuit design with fewer external parts to be realized
depending on use conditions.
YDA148 features Power Limit Function, Non-clip Function, and DRC (Dynamic Range Control)
Function that were developed by Yamaha original digital amplifier technology.
YDA148 has overcurrent protection function for speaker output terminals, high temperature protection
function, and lowsupply voltage malfunction prevention function.
I601 TPA6113A2
The TPA6113A2 is a stereo audio power amplifier packaged in an 8-pin SOIC package capable of
delivering 40mW of continuous RMS power per channel into 16-
Ω
loads Amplifier gain is extermally
configured by means of two resistors per input channel and does not require external compensation for
settings of 0 to 20 dB.
I202 MSD809
The MSD809 is a DTV receiver, which contains a digital receiver compatible with ATSC 8-VSB mode
for terrestrial broadcasting and open cable (SCTE DVS-031) which is in compliant with 64-QAM and
256-QAM modes for digital cable appliances.
It achieves extremely high performance employing direct IF sampling architecture,robust
synchronization, and robust channel equalization. It contains a 12-bit A/D converter and a PWM
generator for automatic gain control. A host interface with an I2C bus is also included to control the
behavior of the MSD809.
