All active dedicated output pins including JTAG TDO pins operate at output standard set to LVCMOS, 12 mA drive, fast slew rate.
Refer UG470 for details.
RTCK is JTAG connector pin for PS based devices and Zynq 7000 doesn't support that. Not sure on what specific application you plan to use this. May be you can reach to TI for its drive strength based query.

This is JTAG pin which would be lvcmos or lvttl of 12mA Drive strength .
