The S8401 and S8501 transmitter and receiver pair
are designed to perform HD-SDI over fiber optic or
coaxial cable interfaces conforming to the require-
ments of the SMPTE 292M. The chipset supports
1.485 Gb/s with an associated 20-bit data word.
The chipset performs parallel-to-serial and serial-to-
parallel conversion for scrambled data. The S8401
on-chip PLL synthesizes the high-speed clock from a
low-speed reference. The S8501 on-chip PLL syn-
chronizes directly to incoming digital signals, to receive
the data stream. The transmitter and receiver each
support differential PECL I/O for fiber optic compo-
nent interfaces, to minimize crosstalk and maximize
data integrity. Local loopback allows for system diag-
nostics.
The S8401 and S8501 operate from +3.3V power
supplies. Each chip typically dissipates only 0.70 and
0.90W respectively. Figure 1 shows a typical network
configuration incorporating the chipset.
