Clocking
2x Word Clock Inputs on 2x BNC connector, accepts standard word clock at
32, 44.1, 48, 88.2, 96, 176.4 or 192kHz. The data rate can be the same as
the clock rate or an exact multiple (such as 0.25x, 0.5x, 1x, 2x, 4x, 8x) of the
clock rate. Sensitive to TTL levels.
The Word Clock Inputs will also accept 38.4kHz word clock from a Vivaldi
DAC set to Universal Master Mode.
Word Clock Output on 1x BNC connector, outputs standard word clock at a
frequency equal to the (single wire) output data rate, or 44.1kHz when set to
output DSD.
Upsampling rates
Data from any input may be converted to 24 bit PCM at 32, 44.1, 48, 88.2,
96, 176.4, 192, 352.8 or 384kS/s or DSD/64 (1 bit data at 2.822MS/s). The
output sample rate must be equal to or greater than the input sample rate.
