External oscillator with ADAU1701 and multiple I2C codecs
Hey all, I'm new to the SigmaDSP platform and am currently working on several of my own designs using the ADAU1701 and ADAU1452. I also intend to use an external oscillator with at least the 1701 for

ADAU1701 DSP Crystal stop oscillating
We have been in production with an ADAU1701 design for 3 years but we have recently been seeing failures that we have identified as the DSP crystal oscillator stopping. This has probably been happenin

ADAU1701 works with active xtal?
Hi Guys, 1) I want to know if ADAU1701/1401 works with Active Xtal ( 4 Pins ones, with GND, Vcc and Out ), if yes, a) Out is to be connected to MCLKI? b) OSC0 is left floating? 2) Also, i want to know

ADAU1701 crystal startup issue
I'm experiencing some problems with crystal. This is what's happening, most of the time when i power on the board (my own design) the crystal doesn't startup, if i touch the trace connected to MCLKI p

ADAU1701 /1401 Recommended Crystal Layout
Dear Analog, We have designed a system using the ADAU1701 and have experienced inconsistent communication to the unit over I2C and SPI. We have narrowed it down to the crystal oscillator being at faul

Crystal Start-Up and PCB Layout
In the system shown below, there were intermittent failures on the crystal startup for several units. The device in the middle is the ADAU1701. C71 and C77 are the load capacitors and R88 is the dampi

Crystal Selection
Exact 12.288MHz crystal is not available in the nearby market. Can I use a 12.000MHz crystal. Since I am using only the analog input and outputs... it wouldn't matter if the sampling frequency is not
