ZL50051 ZARLINK [Zarlink Semiconductor Inc], ZL50051 Datasheet - Page 21

• Manufacturer Part Number: ZL50051
• Description: 8 K Channel Digital Switch with High Jitter Tolerance, Single Rate (8 or 16 Mbps), and 64 Inputs and 64 Outputs
• Manufacturer: ZARLINK [Zarlink Semiconductor Inc]

2.3
The ZL50051 accepts a frame pulse (FP8i) and generates two frame pulse outputs, FP8o and FP16o, which are
aligned to the master frame pulse. The ZL50053 only generates one frame pulse output, FP8o. There is a constant
throughput delay for data being switched from the input to the output of the device such that data which is input
during Frame N is output during Frame N+2.
For further details of frame pulse conditions and options, see Section 13.1, “Control Register (CR)”, Figure 16,
“Frame Boundary Conditions, ST-BUS Operation”, and Figure 17, “Frame Boundary Conditions, GCI-Bus
Operation”.
