KAD5512HP-25, KMB001 Motherboard
For Use With
KMB001LEVAL - MOTHERBOARD FOR LVDS ADC CARD
Lead Free Status / RoHS Status
Lead free / RoHS Compliant
The two analog input circuits are both
transformer-coupled. The path marked Lo Frequency
Input uses two back-to-back Mini-Circuits ADT1-1WT
transformers. This path provides good performance for
input frequencies between 1MHz and 100MHz. The Hi
Frequency Input path (default) uses two back-to-back
Mini-Circuits ADTL1-12 transformers, which provide good
performance from 100MHz to 1GHz. To switch to the Lo
Frequency path, remove 0Ω resistors R16 and R17 and
install 0Ω resistors R18 and R20.
KDC5512-Q48EVAL, KDC5512H-Q48EVAL,
KDC5514-Q48EVAL
These daughter cards contain the 48-QFN version of the
product. To switch to the Lo Frequency path, remove 0Ω
resistors R14 and R15 and install 0Ω resistors R16 and
R18.
KDC5612EVAL
This daughter card was designed to allow for two clock
input paths and two analog input paths (for each input).
The clock can be driven through a 4:1 transformer or a
CML buffer. The default clock path is through the Mini-
Circuits TC4-1W transformer (labeled as CLOCK INPUT
XFMR on the PCB). The AC-coupling capacitors in the
buffered path (C48, C51) are not populated. To use the
clock buffer, install 200pF capacitors in positions C48 and
C51 and depopulate the AC-coupling capacitors (C45,
C49) in the transformer path.

Application Note 1433
The two analog input circuits are both
transformer-coupled, and are replicated for each ADC
input. The path marked Lo Frequency Input uses two
back-to-back Mini-Circuits ADT1-1WT transformers.
This path provides good performance for input
frequencies between 1MHz and 100MHz. The Hi
Frequency Input path (default) uses two back-to-back
Mini-Circuits ADTL1-12 transformers, which provide
good performance from 100MHz to 1GHz. To switch to
the Lo Frequency path, remove 0Ω resistors R16, R17,
R22 and R23 and install 0Ω resistors R18, R20, R24 and
R26.
KAD5610P, KAD5510P-50, KAD2708
These products are lower resolution versions of other
products and do not have dedicated daughter cards.
Performance can be evaluated by ordering the higher
resolution card and adjusting the Number of Bits in the
Conditions Dialog as follows:
• KAD5610:
• KAD5510P-50: Order KDC5512-50EVALZ
• KAD2708C:
• KAD2708L:
Order KDC5612EVAL
(Number of Bits = 10)
(Number of Bits = 10)
Order KDC2710CEVAL
(Number of Bits = 8)
