The DUT card
The DUT card can be configured as a serializer card or a deserializer card. The kit comes with 1 card
configured as a serializer and 1 card configured as a deserializer.
Serializer Configuration
To configure a card as a serializer, a transmitter (DS92LV1023) must be mounted in the location labeled
U2. Additionally jumpers J1, J2, J4 and J5 must be set as follows.
J1 – The setting of J1 controls the TCLKR/F*
input. This input can be set statically using J1 or it
can be controlled by a data signal through P1 pin
4. Setting TCLK_R/F* high will cause the
serializer to use the rising TCLK edge to latch
data. Setting TCLK_R/F* low will cause the
serializer to use the falling TCLK edge to latch
data.
J2 - Connect pins 1-2 to tie PWRDN* high or use
a signal through P1 pin 2 to control the serializer
PWRDN* pin.
J3 – Controls the REFCLK input source for a
deserializer so the setting is a ‘don’t care’ when
configured for a serializer.
J4 – J4 should be set in the SYNC position; pins
1-2 connected. This jumper will connect the bus
SYNC/LOCK signal to the SYNC1 input of the
serializer allowing any deserializers on the bus to
request SYNC patterns from the serializer. When
using the DS92LV1224, this jumper is optional
since the device has random lock capability.
J5 – J5 can be set in the DEN position to permanently enable the serializer or it can be left open and the
DEN pin can be driven through pin 14 of connector P2. The REN/DEN* signal is mutually exclusive – that
is when the REN/DEN* is high the REN signal to a deserializer is high (deserializer enabled) and the DEN
signal to a serializer is low (serializer disabled).
Deserializer Configuration
To configure a DUT card as a deserializer, a
receiver (DS92LV1224) must be mounted in the
location labeled U3. Additionally, jumpers J1,
J2, J3, J4 and J5 must be set as follows.
J1 – The setting of J1 controls the TCLKR/F*
input. This input can be set statically using J1 or
it can be controlled by a data signal through P1
pin 4. Setting TCLK_R/F* high will cause the
deserializer to reference Rout data to the rising
RCLK edge. Setting TCLK_R/F* low will cause
the deserializer to reference Rout data to the
falling RCLK edge.
J2 - Connect pins 1-2 to tie PWRDN* high or
use a signal through P1 pin 2 to control the
deserializer PWRDN* pin.
J3 – Controls the REFCLK input source for a
deserializer. In the SMB REFCLK position (pins
1-2 connected), the REFCLK signal is supplied
