2.2 U701/U702(TPS54319RTER)
General Description
The TPS54319 device is a full featured 6 V, 3 A, synchronous step down current mode converter with two integrated MOSFETs.
The TPS54319 device is a full featured 6 V, 3 A, synchronous step down current mode converter with two integrated MOSFETs.
The TPS54319 enables small designs by integrating the MOSFETs, implementing current mode control to reduce external component count, reducing
inductor size by enabling up to 2 MHz switching frequency, and minimizing the IC footprint with a small 3mm x 3mm thermally enhanced QFN package.
The TPS54319 provides accurate regulation for a variety of loads with an accurate ±3.0% Voltage Reference (VREF) over temperature.
Efficiency is maximized through the integrated 45mΩ MOSFETs and 360mA typical supply current. Using the enable pin, shutdown supply current is
reduced to 2 μA by entering a shutdown mode.
Under voltage lockout is internally set at 2.6 V, but can be increased by programming the threshold with a resistor network on the enable pin. The output
voltage startup ramp is controlled by the slow start pin. An open drain power good signal indicates the output is within 93% to 107% of its nominal voltage.
Frequency fold back and thermal shutdown protects the device during an over-current condition.
The TPS54319 is supported in the SwitcherPro™ Software Tool at www.ti.com/switcherpro.

2.3 U1011(MT5135AE/A)
General Description
MT5135AE is an integrated channel demodulator for European TV solutions. It provides high performance DVB-T and DVB-C demodulation function with
low overall costs. The integrated SAW filter technology eliminates the need for on-board SAW filters and VGAs, resulting in a lower BOM cost and a more
compact PCB design. The integrated CI+ controller and interface also reduce the complexity of TS routing.
The integrated DVB-T and DVB-C demodulators fully comply with the related ETSI and ITU standards. They meet performance requirements of NorDig
Unified, C-Book, and D-Book. A high-performance analog front-end, consisting of a PGA and a 10-bit ADC preceding the digital data path, can accept the
IF or low-IF signal inputs directly from RF can tuners or silicon tuners. The digital data path realizes a set of refined algorithms to achieve quality
demodulation under varying channel conditions and impairments. An on-chip micro-processor controls the robust acquisition flow for both DVB-T and
DVB-C demodulators, and thus enables MT5135AE to successfully lock on the desired TV channel with a high carrier frequency offset (CFO) or timing
frequency offset (TFO). In addition, proprietary mechanisms are incorporated to speed up the channel scan. They include the automatic mode
detection for DVB-T, and the automatic symbol rate and modulation type detection for DVB-C.
With MT5135AE, the cost and system complexity of a TV can be significantly reduced. Taking advantage of the integrated SAW filter technology, the SAW
filter together with the accompanying VGA, conventionally found on board or inside a NIM, can be spared. This solution calls for a simple RF tuner directly
feeding the IF inputs of MT5135AE, leaving a lean PCB design with a smaller component count and a lower BOM cost as well. Furthermore, MT5135AE
provides an integrated CI+ controller with the complete complementing interfaces among the CAM, the main decoder chip, and an additional demodulator
chip. When not in use, these interfaces can be set to hi-impedance mode to support multiple demodulators or multiple CAMs operation. With the highly
flexible CI+ controller and interfaces, MT5135AE effectively addresses the TS routing complexity for the application scenarios such as simultaneous PVR
recording and playback, or time-shift playback. The need for on-board TS multiplexers is eliminated and the PCB layout can be kept as compact as
possible.

The TAS5717/TAS5719 is a 10-W/15-W, efficient, digital audio-power amplifier for driving stereo bridge-tied speakers. One serial data input allows
processing of up to two discrete audio channels and seamless integration to most digital audio processors and MPEG decoders. The device accepts a
wide range of input data and data rates. A fully programmable data path routes these channels to the internal speaker drivers.
The TAS5717/9 is a slave-only device receiving all clocks from external sources. The TAS5717/TAS5719 operates with a PWM carrier between a 384-kHz
switching rate and a 352-KHz switching rate, depending on the input sample rate. Oversampling combined with a fourth-order noise shaper provides a flat
noise floor and excellent dynamic range from 20 Hz to 20 kHz.
