DVB-S2X Modulator

Overview

The Creonic DVB-S2X high performance modulator performs all tasks of an inner transmitter. The modulator expects BBFrames after mode adaptation as input and
performs stream adaptation, FEC encoding, mapping, PL framing and modulation. In addition the core can perform baseband interpolation and output gain adjustment. The
output of the core is designed to be followed by a DAC and RF front end.

Key Features

Compliant with DVB-S2 and DVB-S2X
Supports ACM, CCM, and VCM modes
Support for short and normal frames (16,200 bits and 64,800 bits)
Support for QPSK to 256-APSK,VLSNR modes on request

Benefits

Validated against the field-proven Creonic DVB-S2X demodulator and decoder IP cores.
Easy-to-use mode adaptation input interface.
Provides interpolated and gain-adjusted ZF baseband signal.
The modulator contains padder, BB scrambler, BCH encoder, LDPC encoder, bit interleaver, bit mapper, dummy PL frame insertion, PL signalling, pilot insertion, PL scrambler, baseband filter, interpolator, and gain adjustment.
Can be complemented with the Creonic DVB-CID modulator.
Low-power and low-complexity design.
Memory-mapped interface for controlling and for retrieving status information.
Flexible output interface, which can be driven by an external clock for easy synchronization with DAC
Available for ASIC and FPGAs (Xilinx, Intel, Microchip).
