Ck410 Clock Groups; Platform System Clock Reference; Ref - Intel EP80579 Manual

Platform System Clock—Intel
The CK410 pins require the following stuffing options:
• The series resistor, designated as Rs (33 Ω), and parallel resistor, designated as Rt
(49.9 Ω), are required for CK410 output differential clock
• The series resistor, designated as Rs (33 Ω) is required for CK410 output single-
ended clock
