hi, can you confirm if this is suited to receive the optical toslink audio output of my HD television and output the audio signal via a stereo pair of RCA's to a pair of RCA inputs of my preamplifier?

HI mp9, the dac will be compatiable for the optical toslink and coaxial digital signal, you may check the digital format of your HD television,if the sample rate is 32/44.1/48 KHz

You may need an additional transformer to finish the PSU part,
a 15VA~20VA transformer with AC 15V*2 and 7V*1

Ofcoure this will work, but I have not test it yet.
Maybe I should remove the SAA1315H and then set the I2S input to SAA7220P/B

Hi woodturner, I test the DAC with my PCM2707 USB DAC module, it works fine.
But with USB module,the performance is not so good comparing to COAXIAL input

the configuration :
PCM2707 -- SAA7220
LRCK ----- PIN 1 WSAB
BCK ------ PIN 2 CLAB
DATA -- PIN 3 DAAB
WCK(system) - PIN 11 XIN



This is the RMAA TEST for PCM2707-I2S-TDA1541 OS DAC KIT
Frequency response (from 40 Hz to 15 kHz), dB +0.08, -0.27 Very good
Noise level, dB (A) -95.9 Excellent
Dynamic range, dB (A) 94.6 Very good
THD, % 0.0024 Excellent
THD + Noise, dB (A) -86.5 Good
IMD + Noise, % 0.0063 Excellent
Stereo crosstalk, dB -95.9 Excellent
IMD at 10 kHz, % 0.0082 Very good
General performance Very good
