MxL692
Product Brief
Single-Chip ATSC/QAM Tuner and Demodulator
General Description
The MxL692 is a single-chip, integrated tuner and
demodulator receiver that targets digital TV,
single/multi-channel STB, USB/WiFi adapter, and
WiFi/wired/RF Smart antenna system applications for the
Advanced TelevisionSystmes Committee ATSC standard
and cable applications for the global digital cable standards
ITU-T J.83 Annexes (A, B, and C).
The MxL692 takes an RF input signal from 44 MHz to
1006 MHz, and outputs an MPEG TS in serial or parallel
format. With its high-level of integration, the chip integrates
the following to simplify the board-level design:
■Broadband input filter
■Channel filter
■AGC
■LO
■PLL
■Demodulators
The device comes in a small 5 × 5 mm QFN package,
enabling a very compact design, reduced BOM cost, and
lower power consumption.
The MxL692 is controlled through an I2C interface. The IC
supports either single supply operation using 3.3V, or dual
supply operation using 3.3V and 1.8V.
Applications
■Single-channel ATSC zapper
■Dual-channel PVR STB
■Quad-channel PVR STB
■ATSC/QAM gateway
■ATSC to USB/WiFi adapter
■ATSC wired/RF Smart antenna
Features
■Wide tuning range from 44 MHz to 1006 MHz
■Single RF input
■Integrated channel filtering that does not require SAW
filters, and has programmable channel bandwidths of
either 6 MHz or 8 MHz
■Loop-through (LT) output function
■On-chip voltage regulators enable a single supply
operation
■Typical low-power consumption of <550 mW for ATSC
and <450 mW for QAM in dual supply operation
■Excellent immunity to LTE and WiFi interference
■Automatic spectral inversion in QAM modes
■Input power reporting
■Serial or parallel TS interface
■CEA-909 compliant Smart Antenna Interface
Specification (modes A and B)
■API-based software interface
Supported Standards
■ATSC A/53
■ITU-T J.83
Annex A (DVB-C)
Annex B (US Cable)
Annex C (Japan)
