S2075
FIBRE CHANNEL BIT STREAM MONITOR WITH REPEATER
May 15, 2000 / Revision A
The COM_DET output signal is ACTIVE whenever
EN_CDET is active and the comma control character
is present on the RX[0-9] parallel data outputs. The
COM_DET output signal will be INACTIVE at all
other times.
Parallel Output Clock Rate and Data Stretching
The S2075 supports both full rate and half rate out-
puts, selected via the RATEN input. Table 5 shows
the operating rate scenarios. When RATEN is INAC-
TIVE, a data clock is provided on RBC1 at the data
rate. Data should be clocked on the rising edge of
RBC1. When RATEN is ACTIVE the device is in full
rate mode, and complementary TTL clocks are pro-
vided on the RBC0 and RBC1 outputs at 1/2 the
data rate as required by the Fibre Channel standard.
Data is clocked on the rising edges of both RBC0
and RBC1. See Figures 8 and 9.
Fibre Channel and Gigabit Ethernet standards re-
quire that the comma sync character appears on the
rising edge of the RBC1 signal. In full rate mode the
phase of the data is adjusted such that this require-
ment is met. No alignment is necessary when the
S2075 is operating in half rate mode since the output

Table 5. Operating Rates
clock frequency is equal to the parallel word rate
(RATEN INACTIVE).
In ethernet applications it is illegal for multiple con-
secutive comma characters to be generated. How-
ever, multiple consecutive comma characters can
occur in serial backplane applications. The S2075 is
able to operate properly when multiple consecutive
comma characters are received: after the first
comma is detected and aligned, the RBC0/RBC1
clock operates without glitches or loss of cycles. Ad-
ditionally, COM_DET stays high while multiple com-
mas are being output.
Receive Latency
The average receive latency is 8 byte times.
