GENERAL DESCRIPTION
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.

... Clock and data recovery from serial input 2. Serial-to-parallel conversion 3. 20-bit parallel output The 20-bit parallel data handled by the S8401 and S8501 devices should be from a DC-balanced en- coding scheme, such as the scrambling as defined by SMPTE-292M. Internal clocking and control functions are transpar- ent to the user. Details of data timing can be seen in Figure 5 ...

... The shift register is clocked by the internally gener- ated bit clock which is 20 times the REFCLK input frequency. The state of the serial outputs is controlled by the output enable pins, OE0 and OE1. D[0] is transmitted first. Figure 4. S8501 Functional Block Diagram LOCKREFN REFCLK RX RY 2:1 ...

... Received data from the incoming bit stream is provided on the device’s parallel data outputs. The S8501 accepts serial encoded data from a fiber optic or coaxial cable interface. The serial input stream is the result of the serialization of scrambled data by a compatible transmitter ...

... It also allows system diagnostics. Operating Frequency Range The S8401 and S8501 are optimized for operation at the HD-SDI rate of 1.485 Gb/s. A REFCLK must be selected to be within 100 ppm of the desired byte or word clock rate. ...
