MAX9205 Evaluation Kit

_______________________________________________________________________________________
Quick Start
The MAX9205 EV kit is a fully assembled and tested
surface-mount board. Follow the steps below for EV kit
circuit board operation.
Do not turn on power supply
or enable the function generators until all connec-
tions are completed.
Recommended Equipment
3.3VDC power supply
Data generator for LVCMOS/LVTTL 10-bit parallel
signal input (e.g., Tektronix DG2020)
Clock pulse generator (e.g., HP 8130A)
Logic analyzer or data-acquisition system
High-speed oscilloscope
Procedure
1) Verify that there is a shunt across pins 1 and 2 of
jumpers JU1 and JU3
–
JU7.
2) Verify that JU2 does not have a shunt.
3) Connect the 3.3V power supply to VCC1. Connect
the ground terminal of this supply to GND1.
4) Connect the data generator to the 24-pin connector J1
and set it to generate 10-bit parallel data at
LVCMOS/LVTTL levels (high-level input from 2.0V to
VCC and low-level input from 0.8V to GND). See
Table 2 for input bit locations.
5) Connect the pulse generator to SMA connector
TCLK and set it for an output with a frequency of
16MHz to 40MHz. Use LVCMOS/LVTTL levels. Note
that the TCLK SMA connector is terminated with a
50
resistor. Synchronize the pulse generator with
the data generator.
6) Set the data-acquisition system for LVCMOS/LVTTL-
level signal input.
7) Connect the data-acquisition system to the signal
output 24-pin connector J2. See Table 2 for output
bit locations.
8) Turn on the power supply.
9) Enable the pulse generator.
10)Enable the data generator.
11)Enable the data-acquisition system and begin sam-
pling data.
Detailed Description
The MAX9205 EV kit is a fully assembled and tested cir-
cuit board that simplifies the evaluation of the MAX9205
400Mbps maximum data transfer rate, 10-bit serializer
and the MAX9206 400Mbps maximum data transfer
data rate, 10-bit deserializer. The serializer/deserializer
data transfer starts with the serializer initially locking
onto the reference clock and then sending synchroniz-
ing patterns to the deserializer. Once the deserializer
locks onto the embedded clock in the patterns, it pulls
the SYNC pin low on the serializer, signaling that it is
ready to receive the serial data. The serializer trans-
forms the LVCMOS/LVTTL-level 10-bit parallel data pat-
tern into a serial high-speed BLVDS data stream. The
interconnect is terminated with 100
at each end of the
differential bus for a total 50
load. The MAX9206
deserializer accepts the serial data from the MAX9205
and transforms it back to 10-bit-wide LVCMOS/LVTTL
parallel data.
The EV kit requires a single 3.3V supply to operate and
a reference clock input in the 16MHz to 40MHz range.
The 10-bit parallel input data can be supplied to the 24-
pin header J1 with a data generator running at the
