Packet Telecommand Decoder

DS3839-7.0 September 2001

The MA28140 Packet Telecommand Decoder (PTD) is a

single-chip implementation of the core part of a telecommand

decoder, manufactured using CMOS-SOS high performance,

radiation hard, 1.5µm technology. The PTD is a full

implementation of and fully compliant with the packet

telecommand standard ESA PSS-04-107 and the

telecommand decoder specification ESA PSS-04-151, these

being derived from the corresponding CCSDS standards.

The PTD, which handles 6 NRZ TC input channels,

processes the following layers:

Coding Layer

Transfer Layer

Segmentation Layer

Authentication Layer

Command Pulse Distribution

Some of these layers have a telemetry reporting

mechanism. The processed TC segment can be transferred to

the application either serially or in parallel.
