Table 2-2: Dynamic Switching Behavior During a Handshaking Process
Case Description
1 The handshaking process attempts to switch to select
xcvr_refclk_alt
.
tx_clkout
success‐
fully locks to
xcvr_refclk_alt
(148.35 MHz).
2 The handshaking process attempts to switch to select
xcvr_refclk
.
tx_clkout
successfully
locks to
xcvr_refclk
(148.5 MHz).
3 The handshaking process attempts to switch to select
xcvr_refclk_alt
. The switching fails
because
ch1_{tx/du}_tx_pll_sel
changes from 1 to 0 prior to the assertion of
ch1_{tx/
du}_tx_start_reconfig
. Therefore
tx_clkout
is still locked to
xcvr_refclk
(148.5MHz).
Resource Utilization
The tables below list the typical resource utilization for the SDI II IP core with the Quartus II software,
version 15.0.
Note: The resource utilization data was obtained by using the most common configurations for each
video standard and from one specific family device.
