Features
1. Features
Integrated RF Tuner for DVB-T
− Built-in RF tuner to support DVB-T receptions
at UHF band and VHF band.
− Zero-IF direct conversion architecture to
achieve low power consumption.
− Single-ended RF input eliminates the
requirement of Balun.
− No external SAW filter is required.
− Integrated LNA with low noise figure to meet
MBRAI 2.0 requirement and achieve superior
sensitivity performance without the need of
external LNA.
− Integrated Received Signal Strength Indicator
(RSSI) for precise AGC adjustment in the
environments with Adjacent Channel
Interferences (ACI).
− Automatic RF/BB AGC gain distribution to
properly compromise the performance between
noise and linearity.
Superior DVB-T COFDM Reception
− Complete OFDM demodulation compliant to
DVB-T specification ETSI 300 744, including
Annexes F and G.
− Performance compliant to NorDig Unified v2.0,
D-Book, E-Book, Taiwan BSMI, and MBRAI2.0.
− Robust immunity to Doppler Effect in mobile/
portable reception.
− Superior dynamic echo performance which
meets NorDig and MBRAI echo inside and
outside guard interval tests.
− Diversity-enabled dual channel receiving
capability enabling high mobility DVB-T
reception, picture-in-picture (PIP), and record
while watching (PVR) applications.
− Automatic 2K/4K/8K mode and guard interval
detection.
− Digital carrier frequency offset correction up to
± 500KHz.
− Digital crystal frequency jitter compensation up
to ± 100ppm.
− All-digital time and frequency synchronization
tracking loop.
− All-digital adjacent channel interference (ACI)
rejection filtering for supporting 5/6/7/8MHz
bandwidth.
− Adaptive co-channel interference (CCI) filtering
for interferences including PAL/ SECAM/NICAM.
− Effective impulse noise rejection
− Fast channel scan and switch time.
Versatile Interfaces
− Embedded USB 1.1 and 2.0 compatible
interface support with suspend mode.
− Serial and parallel MPEG2-TS output interface
with simple two-wire control bus.
− Infrared (IR) interface provided for remote
control.
− Multiple sets of PWM and GPIO for external
control purpose.
Compact for Application Designs
− Single crystal (12MHz or 20.48 MHz) is only
required to provide all internal clocks.
− On-chip LDO provides the flexibility of system-
wise power design.
− Single power supply (3.3V) is only required,
with the option of using external 1.2V.
− Superior all-CMOS SoC technology enables
ultra-low power consumption (minimum
200mW core power consumption operating at
8MHz, 8K mode, 64QAM, and code rate 7/8 with
Transport Stream output)
− Single-ended RF input eliminates the
requirement of Balun.
− High sensitivity and ACI immunity are achieved
without external LNA.
Simple Application Programming Interface
with Complete SW Package
− Complete API for fast and easy integration with
application processors, multimedia
processors, or CPU-based platforms.
