Typical Data Rate vs Cable Length Curve

DATA RATE VS CABLE LENGTH TEST PROCEDURE
The Data Rate vs Cable Length graph was generated using National Semiconductor’s CLINK3V48BT-112 Evaluation Kit and 3M’s
Mini D Ribbon (MDR) Cable under typical conditions (Vcc = 3.3V, Temp = +25°C). A Tektronix MB100 Bit-Error-Rate Tester (BERT)
was used to send a PRBS (2
15
) pattern to 32 of the 48 input channels on the transmitter (DS90CR483A). The BERT was also used
to monitor the corresponding 32 receiver (DS90CR484A) output channels for bit errors. The frequency of the input signal were
increased until bit errors were reported on the BERT. The frequency on the graph is the highest frequency without error.
Results:
The DS90CR483A/DS90CR484A link was error free at 100MHz over 10 meters of 3M cable using pre-emphasis and DC balance
mode off.
