S2060 OVERVIEW
The S2060 transmitter and receiver provide serial-
ization and deserialization functions for block en-
coded data to implement a Gigabit Ethernet
interface. The S2060 functional block diagram is de-
picted in Figure 2. The sequence of operations is as
follows:
Transmitter
1.10-bit parallel input
2. Parallel-to-serial conversion
3. Serial output
Receiver
1. Clock and data recovery from serial input
2. Serial-to-parallel conversion
3. Frame detection
4. 10-bit parallel output
The 10-bit parallel data input to the S2060 should be
from a DC-balanced encoding scheme, such as the
8B/10B transmission code, in which information to be
transmitted is encoded 8 bits at a time into 10-bit trans-

Loop Back
Local loopback provides a capability for performing
off-line testing. This is useful for ensuring the integ-
rity of the serial channel before enabling the trans-
mission medium. It also allows for system
diagnostics.
