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.
