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 Cyclone V GX, GT, SX, and ST Devices table.

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 rate above 700
Mbps and 0.00 V to 1.85 V for data rate below 700 Mbps.

There are no fixed VICM, VOD, and VOCM specifications for BLVDS. They depend on the system topology.
For more information about BLVDS interface support in Intel devices, refer to AN522: Implementing Bus LVDS Interface in Supported
Intel Device Families.

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 0.300 V to 1.425 V.
