Notes to Table 1â32:
(1) The 1.5 V PCML transceiver I/O standard specifications are described in âTransceiver Performance Specificationsâ on page 1â21.
(2) VIN range: 0 <= VIN <= 1.85 V.
(3) RL range: 90 <= RL <= 110 ï .
(4) The RSDS and mini-LVDS I/O standards are only supported for differential outputs.
(5) The LVPECL input standard is supported at the dedicated clock input pins (GCLK) only.
(6) There are no fixed VICM, VOD, and VOCM specifications for BLVDS. These specifications depend on the system topology.
