Product supplier Digi-Key now carries Akros Silicon’s new AS1602, a single-chip, highly-integrated CMOS solution for EMI and ESD suppression in Ethernet applications.
The AS1602 can be used in any type of 10Base- T/100Base-TX/1000Base-T systems, in both Power-over-Ethernet (PoE) and non-PoE ports. Applications include compliance to EMI emissions (CISPR22 and FCC Part 15, Class B requirements for radiated and conducted emissions); EMI immunity standards (IEC61000-4-3/6 requirements for radiated and conducted immunity, Level 3 or higher); IEC61000-4-2 air/contact discharge protection (±25 kV Air, ±12 kV contact); and cable discharge event protection (±12 kV).
The AS1602 utilizes Akros Silicon’s patented “active choke technology” to enable better common mode (CM) noise reduction and CM immunity compared to passive filtering techniques in Ethernet applications. At the system level, the AS1602 provides additional CM noise suppression of more than 10 dB over the entire Ethernet signal bandwidth. The AS1602 works with standard Ethernet physical layer transceivers (PHY) and Ethernet transformers. System designers can use the AS1602 to design systems for EMC compliance while maintaining full Ethernet electrical compliance per the IEEE 802.3 specification.
