Field Function
Enter Synthesized port Specifies the speed of the port. For transparent mode circuits, the port
rate (KHz) speed is the sample rate for user data. Therefore, the port rate should be
a multiple of the user data rate. In networks without bandwidth constraints,
we recommend a multiple of 10.
Enable adaptive Specifies whether adaptive clocking is enabled for this circuit.
clocking?
If both end nodes are not locked to a clock reference, we recommend that
you enable one end (not both) for adaptive clocking
Initialize adaptive If you enabled adaptive clocking, specifies whether or not to initialize
clocking parameters? adaptive clocking parameters to their default values, which depend on
y[n]: y port speed, packet size, and buffering parameters set on the bundle.
We recommend the following settings:
Enable 16 bit FIFO? Enables or disables the phase-correction FIFO buffer. This FIFO buffer
aligns the clock and data phase relationship on a TRANS encoded circuit
in which the clock travels in one direction and the data travels in the
opposite direction.
Enable this FIFO buffer at one end of the circuit, but not at both ends.
Invert FIFO Write clock? Specifies whether or not to invert the FIFO write clock.
Invert FIFO Read clock? Specifies whether or not to invert the FIFO read clock.
