SRC4392 is a new chip from TI combining digital audio interface tranceiver with improved SRC4192 asynchronous sample rate converter core. The highlight of the datasheet is that TI finally coughed up the jitter attenuation curves, and they look better than AD1896...

The TI chip has separate curves for IP and OP dig servo loop response. I am presuming the OP loop attenuates the ref clock jitter and IP loop attenuates jitter from receiver portion of the chip (whic has it's own PLL). The TI has a steeper rolloff, 80dB/decade, compared to the AD chip at about 40dB/decade. However the AD chip starts a little sooner having better attenuation sub 20Hz. The TI chip also has better distortion figures. cheers T |
