GENERAL DESCRIPTION
The S2075 bit stream monitor with repeater facili-
tates high speed serial transmission of data over fi-
ber optic, coax, or twinax interfaces. The device
conforms to the requirements of the ANSI X3T11
Fibre Channel specification, and runs at 1062 Mbps
data rates with an associated 10-bit data word.
The chip provides a repeater function with serial-to-
parallel conversion for monitoring the serial bit
stream. An on-chip PLL performs clock recovery and
data retiming of the serial bit stream. In transceiver
mode, parallel data from the local controller is in-
jected onto the serial bit stream. In this mode, the
transmit PLL synthesizes the high-speed clock from
a low speed reference.
The serial I/O support LVPECL compatible signals
for copper or fiber optic component interfaces with
excellent signal integrity. Local loopback mode al-
lows for system diagnostics. The chip requires a
+3.3V power supply and dissipates 600 mW under
typical conditions.
The S2075 can be used for a variety of applications
including Fibre Channel, serial backplanes, and pro-
prietary point-to-point links. Figure 1 shows a typical
configuration incorporating the chip.
