Product Summary
The PC82573L is a GbE controller. It is a single, compact component with integrated Gigabit Ethernet Media Access Control (MAC) and Physical Layer (PHY) functions. The PC82573L uses PCIe architecture (Revision 1.0a). For desktop, workstation, and value server network designs with critical space constraints, the PC82573L enables a GbE implementation in a very small area.
Parametrics
PC82573L absolute maximum ratings: (1)Tstg, Storage temperature: -40 to 125℃; (2)VCC, DC supply voltage on 3.3V pins with respect to VSS: -0.3 to 6.6 V; (3)VCC, DC supply voltage on 2.5V pins with respect to VSS2: -0.3 to 5.0 V; (4)VCC, DC supply voltage on 1.2V pins with respect to VSSb: -0.3 to 2.4 V; (5)Vin, Input voltage (digital inputs): -1.0 to VCC (3.3) + 0.3 (less than 6.6 V)V; (6)AVin, Analog input voltage (digital inputs): -1.0 to VCC (2.5) + 0.3 (less than 5.0 V)V; (7)RPUD, Pull-up/pull-down Resistor Value: 15 to 50 KΩ.
Features
PC82573L fetures: (1)Optimized transmit and receive queues; (2)IEEE 802.3x compliant flow control with software controlled pause times and threshold values; (3)Caches up to 64 packet descriptors per queue; (4)Programmable host memory receive buffers (256 bytes to 16 KB) and cache line size (16 bytes to 256 bytes); (5)32 KB configurable transmit and receive FIFO buffer; (6)Mechanism available for reducing interrupts generated by transmit and receive operation; (7)Descriptor ring management hardware for transmit and receive; (8)Optimized descriptor fetching and write-back mechanisms; (9)Wide, pipelined internal data path architecture.
