Transmitter, receiver, and input reference clock pins of high-speed transceivers use the PCML I/O standard. For
PCML
transmitter, receiver, and reference clock I/O pin specifications, refer to Table 20 and Table 21.

Notes to Table 19:
(1) The minimum VID value is applicable over the entire common mode range, VCM
.
(2) RL range: 90 ≤RL ≤110 Ω.
(3) For optimized LVDS receiver performance, the receiver voltage input range must be within 1.0V to 1.6V for data rates above 1.25 Gbps and 0 V to 1.85 V for
data rates below 1.25 Gbps.
(4) For optimized RSDS receiver performance, the receiver voltage input range must be within 0.25 V to 1.45 V.
(5) For optimized Mini-LVDS receiver performance, the receiver voltage input range must be within 0.3 V to 1.425 V.
(6) 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.
(7) This applies to default pre-emphasis setting only.
