same frequency as the reference clock or the bits can
be configured by installing shunts across header J1
pins. The output 10-bit parallel data can be sampled at
24-pin header J2 or individual bits can be tested at the
various 2-pin headers installed on the EV kit.
The EV kit circuit can be modified to isolate and evalu-
ate the MAX9205 and MAX9206 independently. While
isolated, the serializer
’
s output can be verified with a
differential probe or connected to category-5 twisted-
pair cable. The deserializer
’
s required LVDS input can
be supplied to the EV kit through category-5 twisted-
pair wire or SMA connectors.
The MAX9205 and MAX9206 serializer/deserializer pair
can be replaced with the MAX9207 and MAX9208 pair
for a higher maximum transfer speed rate of 600Mbps
with a maximum clock frequency of 60MHz.
Power Supplies
The MAX9205 EV kit operates from a single 3.3V power
supply. The serializer and deserializer power and
ground planes are connected with PC board traces
through resistor pads R49 and R50. The EV kit circuit
can be divided into two independent circuits, a serializ-
er and deserializer circuit with dedicated power and
ground planes, by cutting open the PC board shorting
traces at resistor pads R49 and R50. If the EV kit circuit
is divided into two separate circuits, each circuit
requires a 3.3V power supply connected at VCC1 (seri-
alizer circuit) and VCC2 (deserializer circuit).
Independent power and ground planes allow measure-
ments of the deserializer
’
s response to ground shift or
other common-mode effects. See the
Serializer/
Deserializer Circuits
section.
Clock Signal
The MAX9205 EV kit requires a square-wave
LVCMOS/LVTTL input clock signal with a frequency in
the 16MHz to 40MHz range. The clock signal can be
connected to the TCLK SMA connector or to pin 24 in
24-pin header J1. For faster data transfer rates, replace
the MAX9205 (U1) and MAX9206 (U2) serializer/deseri-
alizer pair with the MAX9207/MAX9208 serializer/dese-
rializer pair and supply a clock signal with a frequency
of 40MHz to 60MHz. During independent evaluation of
the serializer and deserializer, supply a clock signal to
each circuit. See the
Serializer/Deserializer Circuits
section. The clock input signal to the serializer and
deserializer can be monitored at 2-pin headers JU14
and JU15. See Table 1 for details.
Input Signal
The MAX9205 EV kit accepts 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). The 10-bit
pattern can be supplied to the EV kit by connecting a
data generator to the 24-pin header J1 or by pulling
selected J1 bit pins to a low LVCMOS/LVTTL state. All
the bit pins on J1 are pulled high (VCC1) with 10k
pullup resistors installed on the 10 input signal lines.
See Table 2 for input bit locations on the 24-pin header
J1. If the serializer circuit is operated independently,
either the parallel input can be serialized or a sync pin
can be driven high to generate sync patterns. If the
deserializer is operated independently, a 12-bit serial
pattern (10 data bits plus 2 frame bits) must be sup-
plied to the deserializer circuit. Refer to the
Initialization
section in the MAX9206/MAX9208 data sheet for details
on the deserializer
’
s input requirements. See the
Serializer/Deserializer Circuits
section for further dis-
cussion of independent evaluation.
Output Signal
The MAX9205 EV kit outputs 10-bit parallel data at
LVCMOS/LVTTL levels on the 24-pin header J2. To
sample the 10-bit pattern, connect an acquisition sys-
tem to J2 or sample the individual bits with a 2-pin
header probe. See Table 2 for the output bits
’
location
on the 24-pin header J2 or Table 3 for the location of
the individual output bits. The recovered clock signal is
located on pin 23 of J2 and can be used as the exter-
nal clock input for the acquisition system.
Power-Down Reset
If no output signal is detected from the deserializer,
perform a power-down reset on the serializer by
momentarily pulling low the
PWRDN
pin using jumper
JU4. (See Table 5 for JU4 operation.)
Serializer/Deserializer Circuits
The MAX9205 EV kit board contains a 10-bit parallel
serializer (MAX9205)/deserializer (MAX9206) circuit
that only requires a 3.3V input power supply, a 10-bit
parallel pattern, an acquisition system, and a clock sig-
nal for simple board evaluation. JU2 is provided to test
the serializer high-impedance (Z) delay time. The EV kit
circuit can be divided into two circuits, a serializer and
a deserializer circuit, for independent evaluation. To di-
