The manufacturer spec sheet does not share any info on the impedance of the chip. Anyone around here know?
PO74G74A
VOH Min=2.4V IOH=-12mA VCC=3V
so
ZOut Max ~ (3-2.4)/0.012= ~ 50 ohm

Cronus 1.3 outputs are actually buffered with PO74G38072A

Specs are the same though.

Cronus - It's about time.
I'm an extremely happy BBB/Hermes/Cronus user, but curiosity got the best of me and I would like to test NDK NZ2520SDA with Cronus.

It is a tiny part and I wonder if it would fit on an unpopulated Rhea module?
If yes, do you think it would make a measurable/audible difference?

Thanks!

I think so, and I don't think so.

Default Cronus Reclocker

Russ,
I have placed a larger order wth Twisted Pear. I am still missing the Cronus Recloker component. Any visibility of when the new batch will be available?


BR,
Zoltan

I ordered a fresh batch (with a minor revision) - I would expect them to arrive in a couple weeks. Version 1.4 will have an optional master clock inverter for the Hermes interface exported master clock. This will help with timing in certain situations where the FF timing requirements were not met.

Sorry for the delay - I have several things in the works at the moment and I have been writing a lot of firmware
