Figure 9–3. SFI-4 Interface Signals
The framer transmits outbound data via TXDATA[15..0] and is
received at the SERDES using TXCLK. TXCLK is derived from
TXCLK_SRC, which is provided by the OC-192 SERDES. The framer
receives incoming data on RXDATA[15..0] from the OC-192 SERDES.
The data received is latched on the rising edge of RXCLK.
provides the data rates and clock frequencies specified by SFI-4. The
modes of TXCLK are specified by the SFI-4 standard. In required mode
(622 MHz clock mode or 1 mode), TXCLK should run at 622.08 MHz. In
optional mode (311 MHz clock mode or 2 mode), TXCLK should run at
311.04 MHz.
