CML Outputs

Likewise, CML outputs need to be terminated to V

CC

 via

a 50 

W

 resistor. If no internal resistors are provided on the

device, 0402 chip resistor pads are provided on the bottom
side of the evaluation board to terminate the CML driver.  If
internal resistors are provided, the V

T

 pins should be wired

to V

CC

.

For CML lab setup and test, operation with negative

supply voltages is recommended to enable the 50 

W

 internal

impedance in the oscilloscope, or other measuring
instrument, to be used as a CML output termination; (V

CC

= 0 V, SMAGND = 0 V, and V

EE

/DUTGND = 

5.0 V,

3.3 V, 

2.5 V, or 

1.8 V).

LVDS Outputs

LVDS outputs are typically terminated with 100 

W

 across

the Q/Q output pair. The 100 

W

 can be added on the

QFN16EVB, but it is not provided on the board, since there
are several user dependent LVDS output measurement
techniques.

For LVDS lab setup and test, a single supply is typically

used, ie. V

CC

 = 3.3 V and DUTGND = 0 V.

Installing the SMA Connectors

Each configuration indicates the number of SMA

connectors needed to populate an evaluation board for a
given device. Each input and output requires one SMA
connector. Install all the required SMA connectors onto the
board and solder the center signal conductor pin to the board
on J1 through J16. Please note that the alignment of the
signal connector pin of the SMA connector to the metal trace
on the board can influence lab results. The launch and
reflection of the signals are largely influenced by imperfect
alignment and soldering of the SMA connector.

Validating the Assembled Board

After assembling the evaluation board, it is recommended

to perform continuity checks on all soldered areas before
commencing with the evaluation process. Time Domain
Reflectometry (TDR) is another highly recommended
validation test.
