LRI64

LRI64 TO VCD FRAMES

Response Frames are delimited by a Start of

Frame (SOF) and an End of Frame (EOF) and are

implemented using a code violation mechanism.

The LRI64 supports these in the one subcarrier

mode, at the fast data rate, only.

The VCD is ready to receive a response frame

from the LRI64 before 320.9µs (t1) after having

sent a command frame.

LRI64 SOF

SOF comprises three parts: (see Figure 12.)

–

an unmodulated period of 56.64µs,

–

24 pulses of 423.75kHz (fc/32),

–

a logic 1 which starts with an unmodulated

period of 18.88µs followed by 8 pulses of

423.75kHz.

LRI64 EOF

EOF comprises three parts: (see Figure 13.)

–

a logic 0 which starts with 8 pulses of

423.75kHz followed by an unmodulated

period of 18.88µs.

–

24 pulses of 423.75kHz (fC/32),

–

an unmodulated time of 56.64µs.
