Note: 1. TX input is terminated inside the module.
2. 1000ΩSD Output pull-down resistor required for TRSL-7XX0G / TRSL-7XX0AG (LVPECL SD Output).
3. Veer and Veet are not internally connected to each other.
4. 50 Ω line pattern and component placements on TD+/TD- and RD+/RD- lines shall be symmetrical for
better impedance matching.
