Pioneer DV-414 Signals
The Sonic Frontiers/Assemblage DAC-3 accepts 96 x 24 data
on either S/PDIF, AES, Toslink, or I2Se inputs.
The Pioneer DV-414 DVD player is one of the few that sends full,
unencrypted 96 x 24 audio data out it's Toslink and S/PDIF outputs.
The question here is whether 96 x 24 signals in the DV-414 can be
sent to the Ultra Analog I2Se transmitter board obtained from
Sonic Frontiers, permitting I2Se operation from 96 x 24 DVDs.
One of the major goals of I2Se is the reduction of data-induced
jitter by providing the clock signals on dedicated lines,
rather than multiplexing them as with S/PDIF and AES/EBU.
A question that comes up is whether the easy to reach traces of the DV-414
present adequately low jitter clock signals to obtain this advantage.
Opening the DV-414 and taking a look inside:
- Most of the signals needed for I2Se appear on
output board jumpers
on those jumpers generally have the right timing.
- Comparing the DV-414 waveforms to the
I2Se timing diagrams
shows where the signal phasing is different and
shows some potential timing issues.
