Chapter 4: Reset Control and Power Down in Stratix IV Devices
Transceiver Reset Sequences
February 2011 Altera Corporation
As shown in
manual lock mode:
1. After power up, assert pll_powerdown for a minimum period of t
2. Keep the tx_digitalreset, rx_analogreset, rx_digitalreset, and
3. After the transmitter PLL locks, as indicated by the pll_locked signal going high
4. Wait for at least t
5. De-assert rx_digitalreset at least t
time between markers 1 and 2).
rx_locktorefclk signals asserted and the rx_locktodata signal de-asserted
during this time period. After you de-assert the pll_powerdown signal, the
transmitter PLL starts locking to the transmitter input reference clock.
(marker 3), de-assert tx_digitalreset. For receiver operation, wait for the busy
signal to be de-asserted. At this point rx_analogreset is de-asserted. When
rx_analogreset is de-asserted, the receiver CDR starts locking to the receiver
input reference clock because rx_locktorefclk is asserted.
rx_pll_locked signal goes high, then de-assert the rx_locktorefclk signal. At the
same time, assert the rx_locktodata signal (marker 8). At this point, the receiver
CDR enters lock-to-data mode and the receiver CDR starts locking to the received
data.
after asserting the rx_locktodata signal.
