Receiver signal detection99 VIDLE-THRESH Receiver signal detect input voltage threshold 75 120 175 mVdiff-pkpk
93 Referenced to RX GND. This specification is also supported before mode configuration.
94 This is supported when the receiver is powered and configured, powered and unconfigured, or unpowered.
95 VRX_MAX and VRX_MIN are before and after configuration.
96 The specified common-mode range is supported when the receiver is powered and configured, powered and unconfigured, or unpowered. This specification is also supported before mode configuration. If squelch detect is used, receiver DC input common-mode voltage should be within 200 mV to 300 mV. Otherwise, use AC coupling capacitors on board.
97 The minimum insertion loss specification assumes a PAM4 transmitter with 800 mVppd. For transmitters with output amplitude adjustment capabilities and can reduce output amplitude to below 800 mVppd, this minimum insertion loss can be further relaxed.
98 COM compliant package and channel.
99 Receiver signal detection values in this table are applicable to PCIe* and similar standards, such as SATA, where a clock pattern like PCIe* EIEOS 500 MHz clock pattern is used.
