Stratix II Architecture
For JTAG chains, the TDO pin of the first device drives the TDI pin of the
second device in the chain. The VCCSEL input on JTAG input I/O cells
(TCK, TMS, TDI, and TRST) is internally hardwired to GND selecting the
3.3-V/2.5-V input buffer powered by VCCPD. The ideal case is to have the
VCCIO of the TDO bank from the first device to match the VCCSEL settings
for TDI on the second device, but that may not be possible depending on
the application. Table 2–20 contains board design recommendations to
ensure proper JTAG chain operation.

Notes to Table 2–19:
(1)
Input buffer is 3.3-V tolerant.
(2)
The nCEO output buffer meets VOH (MIN) = 2.4 V.
(3)
Input buffer is 2.5-V tolerant.
(4)
The nCEO output buffer meets VOH (MIN) = 2.0 V.
(5)
Input buffer is 1.8-V tolerant.
(6)
An external 250-
Ω pull-up resistor is not required, but recommended if signal levels on the board are not optimal.
