Transmitter Only Channel
This configuration contains only a transmitter channel. If you create a Transmitter
Only instance in the ALTGX MegaWizard Plug-In Manager in Basic ×4 functional
mode, use the reset sequence shown in
tx_digitalreset
As shown in
Transmitter Only channel configuration:
1. After power up, assert pll_powerdown for a minimum period of 1s (the time
2. Keep the tx_digitalreset signal asserted during this time period. After you
3. After the transmitter PLL locks, as indicated by the pll_locked signal going high
pll_locked
between markers 1 and 2).
de-assert the pll_powerdown signal, the transmitter PLL starts locking to the
transmitter input reference clock.
(marker 3), de-assert the tx_digitalreset signal (marker 4). The transmitter is
ready to transmit data.
