Marantz DV7600 - Clock Upgrade

[dantwomey]

I was looking for a clock upgrade for the Marantz DV7600 and after reading an article about a modified Marantz DV6500 I realized that these universal players are an unique challenge because they have to produce several different clock frequencies. The article goes on to explain it as....

Just a word on the clock: The original Marantz DV-6500 uses a single master clock at 27MHz. An SM8707FV dual-PLL clock generator IC generates independent audio, video and DSP clock outputs from the master clock. The JLTi modification replaces the stock 27MHz master clock with an improved low jitter TENT Labs design. However, the audio/video jitter performance is still limited by the jitter characteristics of the SM8707FV (20ps for video, and 40ps for audio). I feel a better, but more intrusive design, would need to bypass the SM8707FV for true low jitter performance.

Now I'm left to contemplate. Do I put a low jitter master clock in (27Mhz) and reap limited returns or do I try and hack into the two-channel audio circuit and provide a separate two-channel audio clock at 33.86Mhz?





Or, is there some way to improve the jitter performance of the SM8707FV?
