Figure 2. Typical 5 MBd Interface Circuit.
Figure 3. Guaranteed System Performance with Standard
Cable (HFBR-15X1/25X1).
5 MBd Link (HFBR-15X1/25X1)
System Performance 0 to 70 C unless otherwise specified.
Notes:
1. The propagation delay for one metre of cable is typically 5 ns.
2. Typical propagation delay is measured at P
3. Estimated typical link life expectancy at 40 C exceeds 10 years at 60 mA.
