Parameter Symbol Description Condition Min Typical Max Unit
On-chip termination Receiver differential on-chip termination resistors 65 85 102
80 100 120
Receiver input eye specifications VRX-DIFF-PKPK Receiver input differential peak-to-peak voltage91 1,200 mV
VRX-MAX Receiver input maximum voltage92 1 V
VRX-MIN Receiver input minimum voltage92 –0.3 V
VRX-CM-DC Receiver input DC common-mode voltage93 When squelch detector is not enabled 0 700 mV
When squelch detector is enabled 200 300 mV
TRX-RJ Receiver input random jitter At BER of 10-12 0.15 UIpkpk
TRX-PJ Receiver input periodic jitter (at high frequency94 ) 0.05 UIpkpk
Insertion loss specification IINS-LOSS-10.3125Gb/s_BER10-12 Insertion loss at Nyquist frequency (FBAUD/2)95 At BER of 10-12 -25 dB
Receiver return loss ZRL-DIFF-DC Receiver differential DC return loss –12 dB
ZRL-DIFF-NYQ Receiver differential return loss at Nyquist frequency (FBAUD/2) –6 dB
ZRL-CM Receiver common-mode return loss below 10 GHz –6 dB
Receiver DC impedance RDIFF-DC Receiver differential DC impedance 85 Ω on-chip termination 65 85 102
100 Ω on-chip termination 80 100 120
RCM-DC Receiver common-mode DC impedance 20 25 30
Receiver signal detection96 VIDLE-THRESH Receiver signal detect input voltage threshold 75 120 175 mV
91 This is supported when the receiver is powered and configured, powered and unconfigured, or unpowered.
92 VRX_MAX and VRX_MIN are before and after configuration.
93 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.
94 High frequency is defined as frequencies beyond the CDR loop bandwidth (typically FBAUD/1,667).
95 COM compliant package and channel. Based on 10GKR compliance testing at 10.3125 Gbps.
96 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.
