DUAL SERIAL BACKPLANE DEVICE
GENERAL DESCRIPTION
S2062
S2062
FEATURES
• Broad operating rate range (0.77 - 1.3 GHz)
- 1062 MHz (Fibre Channel)
- 1250 MHz (Gigabit Ethernet) line rates
- 1/2 Rate Operation
• Dual Transmitter with phase-locked loop (PLL)
clock synthesis from low speed reference
• Dual Receiver PLL provides clock and data
recovery
• Internally series terminated TTL outputs
• On-chip 8B/10B line encoding and decoding for
two separate parallel 8-bit channels
• 2x8 Bit parallel TTL interface
• Low-jitter serial PECL interface
• Local Loopback
• Interfaces with coax, twinax, or fiber optics
• Single +3.3V supply, 1.37 W power dissipation
• Compact 21mm x 21mm 156 TBGA package
The S2062 facilitates high-speed serial transmission
of data in a variety of applications including Gigabit
Ethernet, Fibre Channel, serial backplanes, and pro-
prietary point to point links. The chip provides two
separate transceivers which can be operated indi-
vidually for a data capacity of >2 Gbps.
Each bi-directional channel provides 8B/10B coding/
decoding, parallel to serial and serial to parallel con-
version, clock generation/recovery, and framing. The
on-chip transmit PLL synthesizes the high-speed
clock from a low-speed reference. The on-chip dual
receive PLL is used for clock recovery and data re-
timing on the two independent data inputs. The
transmitter and receiver each support differential
PECL-compatible I/O for copper or fiber optic com-
ponent interfaces with excellent signal integrity. Lo-
cal loopback mode allows for system diagnostics.
The chip requires a 3.3V power supply and dissi-
pates 1.37 watts.
Figure 1 shows the S2062 and S2068 in a Gigabit
Ethernet application. Figure 2 combines the
S2062 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.
