5.4.2. Bitstream input interface (SDI, SCKR, BIT_EN) SCL_POL = 0
5.4.2. Bitstream input interface (SDI, SCKR, BIT_EN) SCL_POL = 1
tsdi_setup_min = 2ns
tsdi_hold_min = 3ns
tsckr_min_hi = 10ns
tsckr_min_low = 10ns
tsckr_min_lperiod = 50ns
t_biten (min) = 2ns
5.4.3. SRC_INT
This is an asynchronous input used in "broadcast’ mode.
SRC_INT is active low
t_src_low min duration is 50ns (1DSP clock period)
t_src_high min duration is 50ns (1DSP clock period)
5.4.4. XTI,XTO and CLK_OUT timings
txto = 1.40 + pad_timing (Cload_XTO) ns
tclk_out = 4 + pad_timing (Cload_CLK_OUT) ns
Note: In "multimedia" mode, the CLK_OUT pad is DATA_REQ. In that case, no timing is given between the XTI input and this pad.
