Notes
PES64H16G2 User Manual
• De-emphasis
• Receive equalization
• Drive strength
Switch Partitioning

– IDT proprietary feature that creates logically independent switches in the device
– Supports up to 16 fully independent switch partitions
– Configurable downstream port device numbering
– Supports dynamic reconfiguration of switch partitions
• Dynamic port reconfiguration — downstream, upstream
• Dynamic migration of ports between partitions
• Movable upstream port within and between switch partitions
Initialization / Configuration

– Supports Root (BIOS, OS, or driver), Serial EEPROM, or SMBus switch initialization
– Common switch configurations are supported with pin strapping (no external components)
– Supports in-system Serial EEPROM initialization/programming
Quality of Service (QoS)

– Port arbitration
• Round robin
– Request metering
• IDT proprietary feature that balances bandwidth among switch ports for maximum system
throughput
– High performance switch core architecture
• Combined Input Output Queued (CIOQ) switch architecture with large buffers
Multicast

– Compliant to the PCI-SIG multicast ECN
– Supports arbitrary multicasting of Posted transactions
– Supports 64 multicast groups
– Independent multicast support within each switch partition
Clocking

– Supports 100 MHz and 125 MHz reference clock frequencies
– Flexible clocking modes
• Common clock
• Non-common clock
Hot-Plug and Hot Swap

– Hot-plug controller on all ports
• Hot-plug supported on all downstream switch ports
– All ports support hot-plug using low-cost external I
– Configurable presence detect supports card and cable applications
– GPE output pin for hot-plug event notification
• Enables SCI/SMI generation for legacy operating system support
– Hot-swap capable I/O
 Power Management
– Supports D0, D3hot and D3 power management states
– Active State Power Management (ASPM)
• Supports L0, L0s, L1, L2/L3 Ready and L3 link states
• Configurable L0s and L1 entry timers allow performance/power-savings tuning
– Supports PCI Express Power Budgeting Capability
– SerDes power savings
• Supports low swing / half-swing SerDes operation
