ADM3491AR-REEL7 Frequently Asked Questions (FAQ)
-
Analog Devices provides a recommended PCB layout in the application note AN-1349, which includes guidelines for component placement, routing, and grounding to minimize EMI and noise.
-
Proper termination is critical for high-speed signals. Analog Devices recommends using a 50Ω termination resistor at the receiver end, and a 100Ω differential termination resistor at the transmitter end. Additionally, ensure that the PCB trace impedance is matched to the termination resistors.
-
The maximum cable length supported by the ADM3491AR-REEL7 depends on the specific application and the type of cable used. As a general guideline, Analog Devices recommends keeping the cable length below 10 meters for reliable operation. However, it's possible to extend the cable length up to 20 meters or more with proper signal conditioning and cable selection.
-
The ADM3491AR-REEL7 can be configured for half-duplex or full-duplex operation by setting the appropriate pins and registers. For half-duplex operation, connect the TXEN pin to the RXEN pin and set the HFD bit in the control register to 0. For full-duplex operation, connect the TXEN pin to VCC and set the HFD bit to 1.
-
The power consumption of the ADM3491AR-REEL7 varies depending on the operating mode. In normal operation, the device consumes around 135mW. In shutdown mode, the power consumption is reduced to around 10μW. The exact power consumption can be calculated using the equations provided in the datasheet.
