• Manufacturer Part Number: IDT72T51546
• Description: 2.5v Multi-queue Flow-control Devices 32 Queues 36 Bit Wide Configuration 1,179,648 Bits And 2,359,296 Bits
• Manufacturer: Integrated Device Technology

NOTES:
1. Quadrants can be selected on consecutive cycles.
2. On an RCLK cycle that the ESTR is HIGH, the RADEN input must be LOW.
3. There is a latency of 2 RCLK for the PAEn bus to switch.
