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:
