GENERAL DESCRIPTION
The S2104 facilitates high-speed serial transmission
of data in a variety of applications including Fibre
Channel, serial backplanes, and proprietary point to
point links. The chip provides four separate trans-
ceivers which can be operated individually for a data
capacity of >4 Gbps.
Each bi-directional channel provides parallel to serial
and serial to parallel conversion, clock generation/
recovery, and framing. The on-chip transmit PLL
synthesizes the high-speed clock from a low-speed
reference. The on-chip quad receive PLL is used for
clock recovery and data re-timing on the four inde-
pendent data inputs. The transmitter and receiver
each support differential PECL-compatible I/O for
copper or fiber optic component interfaces with ex-
cellent signal integrity. Local loopback mode allows
for system diagnostics. The chip requires a 3.3V
power supply and dissipates 2.5 watts.
Figure 1 shows the S2104 and S2004 in a Fibre
Channel application. Figure 2 combines the S2104
with a crosspoint switch to demonstrate a serial
backplane application. Figure 3 is the input/output
diagram. Figures 4 and 5 show the transmit and
receive block diagrams, respectively.
