I n satellite broa dca st rece pt ion, i n

environments, such as apartment complexes,

where signal lines are long and the wiring

complicated, reflected waves occur almost

everywhere and thus many diverse multipath

environment exist.

The CXD2816R achieves the industry’s top

level of equalization performance and can

hold problems to a minimum in communal

reception environments. Figure 2 shows

examples of multipath and figure 3 shows the

CXD2816R’s resistance to multipath.

An IQ imbalance can result in incompleteness

in the 90° phase shifter used by the RF IC

quadrature demodulator and differences in the

path lengths between the I and Q channels.

This IC includes an IQ imbalance correction

The newly-developed Sony CXD2816R is a demodulator IC that supports broadcast services

conforming to the DVB-S (Digital Video Broadcasting – Satellite ETSI EN 300 421) European digital satellite broadcast

standard and the follow-on DVB-S2 (ETSI EN 302 307).

The CXD2816R can control peripheral devices that conform to the DiSEqC (pronounced “die-sec”) standard (Digital

Satellite Equipment Control) and supports a wide range of applications.

DVB-S2/S Standard Digital Satellite Broadcast

Demodulator IC Achieves the Industry‘s Top level

of Performance and Low Power Consumption

circuit and can automatically correct phase

and amplitude errors in RF IC I and Q

channels. This can also support substrate

pattern optimization to minimize the board

area required for RF IC connection.

Phase noise increases during rain and due

to performance degradation over time of the

parabolic antenna used and can have severe

adverse influences on reception performance.

In particular, antenna degradation over time

is the most common cause of problems in

satellite broadcast reception.

This IC adopts a newly-developed architecture

and improves the robustness of performance

in environments with phase noise. Figure 4

shows an example of phase noise and this IC’s

resistance to that noise.

DiSEqC is a widely adopted protocol for

controlling parabolic antennas, switches, and

other devices connected to the digital satellite

broadcast set top box by coaxial cable.

The CXD2816R can control devices that

conform to this standard.

In this development effort, we aimed at

increasing the speed of sync acquisition

for DVB-S, which is a lower symbol rate

broadcast standard.

Although 80 ms was required for sync

acquisition in previous devices, we were able

to achieve a high-speed sync acquisition time

Phase Noise Canceller

Capable of Controlling DiSEqC

2.x Compliant Devices

Achieves High-Speed Sync

Acquisition for the DVB-S Standard

of just 16 ms by adopting new algorithms.

Also, by handling broadcast waveforms that

have a large frequency offset, this device

achieves stable, high-speed sync acquisition

even in degraded signal environments. This

contributes to rapid channel switching in

TV sets.

For the DVB-S2 standard, we reduced the

amount of RAM and control the operating

timing according to the noise conditions in the

circuits in the LDPC decoding block, efforts

that required extremely high-level design

technologies. As a result, we achieved smaller

circuits and lower power consumption.

This IC achieves the low power consumption

of 380 mW (typ.) during DVB-S2 reception

and 220 mW (typ.) during DVB-S reception.

This means that end product thermal design

is easier, a heat sync is no longer required,

and the device is appropriate for on-board

designs. It is provided in an 80-pin LQFP

package with a size of 12 × 12 mm.

Low Power Consumption

We revised the design of the phase noise

canceller so that it would always achieve

optimal reception performance with fewer

range of signal reception environments

and antennas that exist in today’s world.

Also, even during reception, this device is

always searching for a variety of control

parameters and continually updating

them so that the control parameter

settings are always optimal. Thus this is

an IC that strives for ease of use in this

aspect as well. We strongly recommend

that you consider this device.
