The recommended power-up sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures proper initialization and prevents latch-up conditions.
The clock input should be driven by a low-skew, low-jitter clock source. A clock frequency of 25 MHz or higher is recommended for optimal performance. Additionally, the clock signal should be terminated with a 50-ohm resistor to prevent signal reflections.
The CY29973AI supports data transfer rates up to 100 Mbps. However, the actual data transfer rate may be limited by the system's clock frequency, bus loading, and other factors.
Interrupts should be handled by the system's interrupt controller or a dedicated interrupt handler. The CY29973AI provides an interrupt output pin that can be connected to the interrupt controller or handler. The interrupt handler should clear the interrupt source and perform the necessary actions to service the interrupt.
The recommended layout and routing for CY29973AI involves keeping the clock signal traces short and away from noisy signals. The power and ground pins should be connected to a solid power and ground plane, respectively. Additionally, the signal traces should be routed to minimize crosstalk and electromagnetic interference (EMI).
