Example: For a 20 MHz Router 5000 device (where both halves use the Router

5000 chip), a measured data transfer rate for sending a service-pin message

between the router halves was approximately 1.2 μs per byte (or 830 kbytes/sec).

Some additional latency was seen for the time between the beginning of the

original packet transmission and the beginning of the forwarded packet

transmission.

For slower channel types, this router latency is not significant, but could become

significant for faster channel types.

The latency between router halves is relatively invariant, with respect to router

configuration, whereas overall router latency depends on the router type and

configuration. For an RTR-10 device, the maximum data transfer rate between

router halves is approximately 2.4 μs per byte (or 416 kbytes/sec). For a Router

5000 device (where both halves use the Router 5000 chip), the maximum data

transfer rate between router halves is approximately 600 ns per byte (or 1.6

Mbytes/sec, assuming a 40 MHz system clock for both halves; this rate scales

with the system clock setting). An FT Router 5000 performs similarly to the

Router 5000.
