PCML
Transmitter, receiver, and input reference clock pins of high-speed transceivers use the PCML I/O standard. For transmitter, receiver,
and reference clock I/O pin specifications, refer to Transceiver Specifications for Arria V GX and SX Devices and Transceiver Specifica‐
tions for Arria V GT and ST Devices tables.

The minimum VID value is applicable over the entire common mode range, VCM
RL range: 90 ≤ RL ≤ 110 Ω.
.
This applies to default pre-emphasis setting only.
For optimized LVDS receiver performance, the receiver voltage input range must be within 1.0 V to 1.6 V for data rates above 1.25 Gbps and 0 V to
1.85 V for data rates below 1.25 Gbps.
For optimized RSDS receiver performance, the receiver voltage input range must be within 0.25 V to 1.45 V.
For optimized Mini-LVDS receiver performance, the receiver voltage input range must be within 0.3 V to 1.425 V.
For optimized LVPECL receiver performance, the receiver voltage input range must be within 0.85 V to 1.75 V for data rates above 700 Mbps and
0.45 V to 1.95 V for data rates below 700 Mbps.
