GENERAL DESCRIPTION:

The VSC8221 is the smallest, lowest power Gigabit Ethernet over copper PHY available and is ideal for SFP/GBIC and Media Converter applications. It is the only triple speed copper SFP PHY to meet the stringent MSA power consumption requirement of 140m of Category 5, unshielded twisted pair (UTP) cable, with industry leading tolerance to NEXT, FEXT, Echo, and system noise.

FEATURES:

► Very Low Power Consumption at < 700mW

► Single 3.3V Power Supply with On-chip Regulator

► Patented, Low EMI Line Driver with Integrated Line Side Termination Resistors

► Supports PICMG 2.16 and 3.0 Ethernet Backplanes at Approximately 500mW

► High Performance 1.25 Gbps SerDes Supports SGMII and SerDes to Cat-5 Interfaces

► Compliant with IEEE 802.3 (10BASE-T, 100BASE-TX, 1000BASE-T, 1000BASE-X) and SFP MSA Specifications

► Full Suite of BIST, MAC, Far-end, and Connector Loopback Modes

► Over 150m of Category-5 Reach with Industry’s Highest Noise Tolerance

► VeriPHY™ Cable Diagnostics Software Suite

► Automatic Detection and Correction of Cable Pair Swaps, Pair Skew and Pair Polarity, Along with Auto MDI/MDI-X Crossover Function

► Several Flexible Power Management Modes

► Manufactured in Advanced 0.13µm, 3.3V/1.2V Digital CMOS Process

APPLICATIONS:
