FS: DIR9001 to CS8412 converter board
2 Attachment(s)
This is a newly completed project for a DIR9001 to be used in CS8412 socket digital receiver DACs. The board is proven working in my D1 Ver2 clone DAC and will also be working in other DAC which accept 16 or 24 bit format as stated in DIR9001 data sheet. The only thing I want to highlight is the low 50ps jitter of DIR9001 compare to old receier 8414/8412 with >200ps jitter.

Price is US$5 with below content:
1. Two 14 pins strip.
2. 4 0.1uF smd chip cap
3. 2 10uF smd chip cap
4. 1 22uF smd chip cap
5. Some 2.5mm pins
6. One smd bead

Buyer pay shipping $1 for normal airmail and $3 for registered airmail. Paypal charge is 4%.

The rest of parts can be ordered from Farnell. Interersted please PM me.

Here is the update BOM as the last one is missing some Farnell part number.

Since some chip parts are not cheap to order small quantity, I shall offer the kit without 3 ICs at US$6. Here is the BOM again.

Interested can PM me.
