Other Parts Discussed in Thread: TAS5828MEVM
Hi,
I tested the cross-talk for TAS5825EVM and found it worse than stated in the datasheet (100dB). Please check if my setup or test condition is proper for this test. Please advise the test condition for "x-talk" in the TAS5825 datasheet( PVDD? impedance connected to spk out1/2? etc)
Phenomenon: crosstalk test 55dB (TAS5825 datasheet: X-talk 100dB@1K)
Test DUT: PurePath Console Motherboard + TAS5825EVM
PurePath Console settings:
Connected I/O on PPC MB: Optical
PVDD: 19V by DC power supply
Measurement point: OUT1 & OUT2 with 4ohm dummy load connected
Signal: 1K_0dBFS and 1K_-20dBFS are send via APx525 optical
Test Result:
55dB
Thank you!
