DESIGN PARAMETER | REQUIREMENTS |
---|---|
Input AC coupling capacitors | AC coupling capacitor at IN0+ should be a 4.7-μF surface mount ceramic capacitor. IN0- should be AC terminated with 4.7 μF and 75 Ω to VSS. |
High speed board trace for IN0 | IN0+ and IN0- should be routed with uncoupled board traces with 75-Ω characteristic impedance. |
BNC connector | High performance BNC capable to support 2.97 Gbps should be used. Footprint of the BNC should be designed to achieve 75-Ω characteristic impedance. For achieving best return loss performance, the BNC should be placed as close to the LMH0324 device as possible |
Output AC coupling capacitors | Both OUT0± and OUT1± require AC coupling capacitors. 4.7-μF capacitors are recommended. |
High speed board trace for OUT0± and OUT1± | OUT0± and OUT1± should be routed with coupled board traces with 100-Ω differential impedance. |
Use of SPI or SMBus interface | Set MODE_SEL to Level-F (pin unconnected) for SPI. Set MODE_SEL to Level-L (connect 1 kΩ to VSS) for SMBus. SMBus is 3.3 V tolerant if VDDIO is powered from 2.5 V. |
