EVAL BOARD USER’S MANUAL
Generic Evaluation Board: XOCLCC6EVB
Devices: NBXxxxx
Description
Evaluation Board Manual Document Features
This Evaluation Board user’s manual is a guide for using
the XOCLCC6EVB Evaluation Board to provide a
convenient platform for quickly evaluating, characterizing
and verify performance and operation of a device in the
NBXxxxx family of Clock Oscillator Modules packaged in
the 6 pin CLCC, 5mm by 7 mm, CASE 848AB (see
Appendix).
This family of devices offer an internal crystal and PLL
IC. This Evaluation Board Manual and Evaluation Board
should be used in conjunction with a specific device data
sheet, which contains full technical details on specifications
and operation.
An NBXxxxx Clock Oscillator Module device may be
directly solder mounted onto the available evaluation board
footprint; or multiple units may be inserted and tested by
solder mounting a separate insertion socket (P/N
AM0393−320R from SER Electronics) onto the available
footprint.

What measurements can you expect to make?
With this evaluation board, the following measurements
could be performed in single−ended or differential modes of
operation.
• DC Characteristics
• Frequency Performance
• Output Rise and Fall Time
• Phase Noise
• Jitter
Evaluation Board Features
• 6 pin CLCC solder footprint for solder mounting a
device or test socket
• Incorporates jumper headers to conveniently and
manually control the levels for the ’Output Enable’
(Pin 1) and ’Frequency Select’ (Pin 2) pins.
• Enable single or split−power supply operation.
LVPECL differential outputs are accessed via SMA
connectors offering different output load configurations.

NOTE: SMAGND is the SMA cable shield reference for

Setup
The following steps should be followed for proper
equipment setup.
Step 2: Connect Output Signals
Table 4 gives a list of specific LOGIC Levels and their
appropriate Power Supply and Typical Lab Setup
conditions
LVPECL: The LVPECL outputs have standard, open
emitter outputs and must be externally DC loaded and AC
terminated. A split power supply technique takes advantage
of terminating the LVPECL outputs into 50 W of an
oscilloscope or a frequency counter. Since VTT = VDD – 2 V,
offsetting VDD to +2.0 V yields VTT = 0 V or Ground
(SMAGND). The VTT terminal connects to the isolated
SMAGND connector ground plane, and is not to be
confused with the device ground pin (DUTGND). (See
Application Note AN8020/D for details on ECL
termination).
CML: For CML lab setup and test, operation with
negative supply voltage is recommended to enable the 50 W
internal impedance in the oscilloscope to be used as a
termination of the CML signals (VDD = 0.0 V, SMAGND =
0.0 V, and DUTGND = −3.3 V (See Application Note
AN8173/D for details on CML termination).
Step 1: Connect Power (split power supply mode)
Three power levels must be provided to the board: VDD,
DUTGND, and SMAGND via the test point anvils at the
edges of the board. Bypass capacitors are installed from
VDD to SMAGND and DUTGND to SMAGND near the test
points (see BOM). Devices may be tested in one of three
supply modes (see Table 3):
A). Single (Positive) +3.3 V Setup
No offset to supplies or output levels
B). Split 3.3 V Setup
Offsets the VDD, DUTGND, and output voltage levels by
−1.3 V and avoids an additional, separate VTT supply and
allows a direct connection to test equipment such as an
oscilloscope or counter with 50 W impedance to GND
inputs. SMAGND = VTT = VDD – 2.0 V = 0.0 V.
C). Single (Negative) −3.3 V Setup
Offsets the VDD, DUTGND, and output voltage levels by
−3.3 V

Step 3: Configure FSEL and OE
LVDS: Driver termination is a 100 W resistor across the
differential lines located at the receiver input.
The FSEL and OE control pins can be controlled from an
external source via the appropriate test point, or via the
jumper headers located on the evaluation board, as indicated
in Figures 2 and 7. Refer to the specific device datasheet for
details on the proper settings for these pins.
