vide the circuit into two circuits, cut open the PC board
trace shorting the resistor pads at R41
–
R45, R49, R50,
R75, remove resistor R39, and install a shorting resistor
on R48.
The MAX9205 (U1) serializer circuit generates two
types of signals, synchronization and serialized data
patterns:
1) Generate synchronization (SYNC) patterns by apply-
ing a high-state LVCMOS signal to pin 2 of the 24-
pin header J1 or the SYNC2 PC board pad.
2) Generate serialized data patterns by asserting a
low-state LVCMOS signal to pin 2 of the 24-pin
header J1 and provide 10-bit parallel data to the EV
kit. For data and clock input signal details, see the
Input Signal
and
Clock Signal
sections, respectively.
The serializer
’
s BLVDS output signal is a 12-bit serial
pattern that consists of a high-state start bit and low-
state end bit, added internally and used by the deseri-
alizer, to the 10-bit parallel input data. Refer to the
MAX9205/MAX9207 data sheet for details. To monitor
the BLVDS output signal, connect a differential signal
probe to JU9 (noninverting single-ended signal) or
JU10 (inverting single-ended signal) or connect twist-
ed-pair cable to PC board vias 1A (noninverting signal)
and 1B (inverting signal). Terminate the twisted pair at
the far end with a 100
resistor for a total 50
load.
See Table 4 for locations and connector type for the
LVDS serial signal output.
To evaluate the MAX9206 (U2) deserializer circuit, pro-
vide a 12-bit BLVDS serial input and a clock signal to
the REFCLK SMA connector. Bit 0 of the 12-bit serial
input pattern should be BLVDS high state and bit 11
should be BLVDS low state with data bit in between.
Refer to the MAX9206/MAX9208 data sheet for further
details on the start and end bits.
The 12-bit BLVDS pattern can be supplied to the dese-
rializer circuit in two ways: with twisted-pair cable or
SMA connectors:
1) Using twisted-pair cable, connect the serial input
signal to PC board vias 2A (noninverting signal) and
2B (inverting signal). Terminate the twisted-pair
cable at the transmitting end with a 100
resistor for
a total 50
load (including the 100
resistor in par-
allel at the deserializer input).
2) With SMA connectors, install shorting resistors at the
R46 and R47 PC board pads and connect the serial
signal through SMA connectors INA (noninverting
signal) and INB (inverting signal). Monitor the integri-
