Hi Tibi,
So do you recommend mini-regs [adj] for V1-V2 or just LT1086 for best performance? I do have salas reflecktor-d's also. If I use reflector-d is there a recommended wiring configuration. Can I use mini-reg on V3-V4 and reflector-d V1-V2 since you can't mix fixed and adj mini-regs? Thanks for time and info!
best regards,
Steve

Hi Steve,

V1 = V2 = V3 = V4 = 5V
Make sure that voltage difference between them is under 100mV.
For example V2 can be 5,050V and V4 = 5,140V, but not 5,200V or 4,900V.

V1 - power laser and Vref section
V2 - power HF analog signal processor LA9242
V3 - power clock section
V4 - power digital signal processing section LC78601

Miniregs can be used in V2,V3 and V4 positions. For V1 you need a more current capable regulator, like LT1086-5. Please note that minireg in V2 position do not make much difference, at least in my system...
If you look for madness resolution, than in V3 position use a Salas D reflector.
For V1, you may use Salas as well. Again resolution is enhanced. This tighten bass even more and you hear everything. Some people may say is too much ... ;-)

If you intend to bring Shiga MII to very high-end top killer, than a Dexa Neutron and Duelund Silver Cast - for C8 -are a must.

Regards,
Tibi

Congrats.

Thanks Karel
As with all these things ... when you improve one part of your signal path it just highlights a weakness elsewhere !! One day I may treat myself to the Dueland Cast in C8 to go with it.

Thanks for information on V1-4! I am building using the high end components. If I use Salas D reflector do you recommend to go directly to V-out and gnd on V_ pcb regulator
pads as it has its own transformer?

I'm not sure that I have understand what you mean. However, I recommend you to use a separate trafo for each Salas, or at least use a trafo with with separate secondary winding's.

Use a single point for GND, for all Salas regs, at the main board power input.

If use a metal enclosure, ground the enclosure from the output S/PDif.

Tibi

Hi Tibi,
I am trying to find information about the 2.5V regulator ADP151-2.5, it is listed with option components if used but I can't find anything regarding it's use. Can you fill me in please or point me in the right direction. Regarding my inquiry about salas d reflector use, my question was regarding 5V out. Can I input at V3 pads on shiga pcb ?Thanks!

best regards,
Steve

Hi Steve,

ADP151-2.5 is there to provide a very stable Vref=2,5V for laser PIN detector. In case you want to implement this, you need to add R65=1K, C68 and C69. C68 and C69 must be at least 1uF. At this value any MLCC is highly piezoelectric, please mount them vertically to minimize this effect, or use a tantalum on C68.

Salas D reflector can be used on any V1=V2=V3=V4=5V. Single condition is to tune them to output under 100mV difference voltage. You may want to load Salas with a 1K resistor.

Regards,
Tibi
