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 (Figure 53).
• The series resistor, designated as Rs (33 Ω) is required for CK410 output single-
ended clock (Figure 53).
