SONY CXD 1144A 8 x Over Sampling TDA1541a Simultaneous Mode

Some testing with SONY Digital Filter CXD 1144 A  and TDA1541A in Simultaneous mode

With some glue logic i created a Pulse to Invert the MSB out off the CXD 1144, so the TDA1541(a) understand the 16 bit word :-), This pulse is also delayed and used for the LATCH ( start DA conversion )

  • Yellow : Pulse signals MSB and used to Invert MSB
  • Blue : Data word in “Complemented Offset Binary”
  • Purple : Dataword converted to “Data Offset Binary”
  • Green : Latch pulse  start DA Conversion

Digital  Silence unditherd

Multitone -20 dBfs
