Hello everyone - this is my first post after reading hundreds of helpful ones, so thank you in advance for everything!
I am trying to put a separate clock into a Pioneer PD-59 (stable platter), and am having a hard time getting the unit to see the clock. The crystal I'm replacing goes into a pioneer legato link PD2029A DAC, and the only pinout I could find is here (from an earlier thread): 1 - S/P 2 - RZ 3 - XTEST 4 - VDA 5 - RO 6 - XRO 7 - GNDA 8 - GNDA 9 - XLO 10 - LO 11 - VDA 12 - GNDX 13 - X1 14 - X0 15 - VDX 16 - GND 17 - C (H384Fs) 18 - LZ 19 - MCK 20 - LATCH 21 - SHIFT 22 - ATT 23 - NC 24 - XRESET 25 - DATA 26 - BCK 27 - LRCK 28 - VDD However, I taking out the crystal and caps to ground, then connecting the third-party clock to Xin as normally does not work. The Legato link doesn't connect both pins of the crystal directly to the resistor in parallel; one side of the crystal goes directly into the DAC. Does anyone have a suggestion? |

So, where have you conected the new clock?
What make is it ? Is it the correct frequency ? Have you conected the ground of the clock to the main ground near the dac ? Post a couple of photos .. they always help. Andy

Also the 1 meg resistor across Xin and Xout should be removed.

I want to replace the clock in one of these but can't find a reference for the clock frequency - does anyone know what it is? And can anyone point me to a schematic or service manual? Thanks
