Table 1. GTY and GTYP Transceiver Reference Clock Switching Characteristics
Symbol	Description	Conditions	All Speed Grades			Units
Symbol	Description	Conditions	Min	Typ	Max	Units
F_{GTY_REFCLK¹}	Reference clock frequency range		60	–	820	MHz
T_RCLK	Reference clock rise time	20% – 80%	–	200	–	ps
T_FCLK	Reference clock fall time	80% – 20%	–	200	–	ps
T_DCREF	Reference clock duty cycle	Transceiver PLL only	40	50	60	%
The frequency values apply when the reference clock buffer is configured as either an input or output.
