ADVANCED MODULATION SATELLITE RECEIVER

S U M M A R Y O F B E N E F I T S

F E A T U R E S

All-digital satellite receiver

Highly integrated solution provides universal frontend for

advanced modulation satellite systems and legacy QPSK

systems in a single package.

•

256-kilobaud to 30-megabaud variable rate receiver

Supports BPSK, QPSK, 8PSK, & 16QAM modulation

Dual integrated 7-bit A/D converters

Digital square-root Nyquist filters (a=0.2, 0.35)

All-digital clock and carrier recovery

High-performance turbo code FEC enables 50% throughput

increase over existing satellite channels within current link

budgets within a single transponder.

12-tap adaptive equalizer

Advanced design architecture requires no external RAM for

turbo FEC.

•

Advanced modulation turbo FEC decoder

High performance decoder approaches constrained capacity

theoretical limits

Advanced modulation receiver maintains robust performance

during low SNR operation.

Supports QPSK rates 1/4, 1/2 and 3/4

8PSK flexible code rate support including 2/3, 3/4, 5/6 and 8/9

Supports 16QAM rate 3/4

No external RAM support required

Reed-Solomon decoder; t=10

Full variable rate operation from 256-kilobaud to 30-

megabaud provides multiple operating points for optimal

system deployment.

Integrated microcontroller controls receiver operations

including configuration, acquisition and performance

monitoring.

•

Complies with DVB/DIRECTV®/Digicipher IITM FEC decoder

MPEG-2 or DIRECTV® output interface with output clock PLL

On-chip microcontroller for acquisition and tracking

On-chip BERT for BER testing

•

Host interface operates via high-level application program

interface (API) to reduce host software development time and

to simplify system integration.

MPEG-2 or DIRECTV® output interface with PLL-generated

data clock provides glueless integration with BCM7020 HD

graphics and video subsystem.

Integrated DiSEqCTM (v2.0) transmitter and receiver

128-pin PQFP

Highly integrated DiSEqCTM interface includes integrated

analog components.
