zl50064 Zarlink Semiconductor, zl50064 Datasheet - Page 28

• Manufacturer Part Number: zl50064
• Description: 16 K Channel Digital Switch With High Jitter Tolerance, Single Rate 2, 4, 8 Or 16 Mbps And 64 Input And 64 Output Streams
• Manufacturer: Zarlink Semiconductor

The data throughput delay (T) is: T = 2 frames + (n - m). Assuming that m (input channel) and n (output channel)
are equal, we have the figure below, in which the delay between the input data being written and the output data
being read is exactly 2 frames.
Assuming that n (output channel) is greater than m (input channel), we have the figure below, in which the delay
time between the input channel being written and the output channel being read exceeds 2 frames.
Assuming that n (output channel) is less than m (input channel), we have the figure below, in which the delay time
between the input channel being written and the output channel being read is less than 2 frames.
