AC Operating Characteristics

SMT1 JTAG signals are driven according to the timing diagram below. JTAG/TCK frequencies from 30 MHz to 8 KHz

are supported, at integer divisions of 30 MHz from 1 to 3750. Common frequencies include 30 MHz, 15 MHz, 10

MHz, 7.5 MHz, and 6 HMz. JTAG/TCK operating frequency can be set from within the Xilinx tools.

Note: Please refer to Xilinx’s iMPACT documentation for more information.
