SM5951A
8-channel DSD Editing System Signal Processor LSI
OVERVIEW
The SM5951A is an 8-channel DSD (Direct Stream Digital) editing system signal processor LSI. It takes 4
DSD input signals per channel, mixes them, and then converts the result back into 1-bit DSD data for output.

8-channel DSD signal mixing
鈥?8-channel, 4 DSD signal inputs per channel mixing using arbitrary coef鏗乧ients for each input
Raw signal switching function (auto bypass)
鈥?Automatically switches to raw signal output with no switching noise and no signal degradation when mix-
ing is not required, bypassing the mixing processing
Input/output format
鈥?Normal input/output format where the data changes are synchronized to the bit clock cycle, and Manches-
ter-type encoding input/output format where the data inverts during the bit clock cycle
Monitor output: Simultaneous 64
