  • WiND502 802.11abg chipset consisting of:
EN202 - MAC/BB, USB interface, CMOS 180nm
EN303 - RFIC 2.4/5GHz
  • WiND512 802.11bg chipset consisting of:
EN202 - MAC/BB, USB interface, CMOS 180nm
EN313 - RFIC 2.4GHz
EN202 (MAC/BB)
  • The EN202 is a highly integrated, triple-mode wireless LAN medium access control (MAC) and baseband (BB) chip,
compatible with 802.11a/b/g wireless standards.
  • Envara's EN202 chip is incorporated into its WiND502 and WiND512 wireless LAN chipset solutions, enabling
a clear migration path for applications using 802.11g technology to advanced 802.11a/g based solutions.
  • The EN202 contains two modems. An orthogonal frequency division multiplexing (OFDM) modem is compatible
with the 802.11a and 802.11g and supports multiple data rates of up to 54 Mbps.
  • A direct sequence spread spectrum/ complementary code-keying (DSSS/CCK) modem supports the 802.11b
standard and supports multiple data rates of up to 11 Mbps.
  • The inherent flexibility of the chip supports many advanced MAC features such as improved security,
low power consumption, system stability and multimedia support.

Key Features

  • Built-in 802.11a / 802.11g and IEEE 802.11b compatible dual-mode OFDM and DSSS/CCK modems.
  • Built-in 802.11 MAC, to support IEEE 802.11 MAC extended features such as Security (802 11i, and WPA),
QoS (802.11e and WPA), and DFS/TPC for compatibility with Worldwide radio regulations (801.11h/d/j).
  • External data bus, enabling connection to additional memory components as well as interface
controllers, such as USB2.0 transceivers
  • Built-in A/D and D/A converters
  • Low power consumption
  • PCI and MII interfaces

Applications

  • WLAN network interface cards (NICs)
CardBus, MiniPCI, Ethernet and USB 2.0 (adapter and dongle) reference designs
  • WLAN access points (AP)
  • Residential gateways

EN303 (RFIC 2.4/5GHz)
  • The EN303 is a monolithic SiGe half-duplex RF multi-band transceiver designed to operate in either the 5GHz unlicensed
frequency band (including all channels starting from 4.9GHz up to 5.9GHz) or in the 2.4GHz unlicensed frequency band.
  • As an integral part of Envara's WiND502 triple-mode chipset, EN303 enables a very low-cost implementation of wireless
LAN (WLAN) equipment such as network interface cards and access points.
  • EN303 is compatible with 802.11a, 802.11b and 802.11g international wireless standards.

Key Features

  • One-World support - Operates within either 4.900~5.825 GHz or 2.412~2.484 GHz frequencies
- supporting 802.11h/g/j requirements
  • Reduced BOM & small footprint
On-chip VCOs, synthesizer, LNAs
Envara's patented Enhanced Zero IF (EZ-IF) architecture enables simpler integration
and lower cost implementation by not requiring external IF or baseband filters
  • High Performance
High input dynamic range
Excellent interference resilience
Improved sensitivity; greater range
  • Power management includes 'stand-by' mode to maximise power efficiency.

Applications

  • WLAN interface cards: MiniPCI, USB 2.0, Ethernet and CardBus PC cards
  • Access points (AP)
  • Residential gateways

EN313 (RFIC 2.4GHz)
  • The EN313 is a monolithic SiGe half-duplex RF transceiver designed to operate in the 2.4GHz
unlicensed frequency band (2.412 - 2.484GHz).
  • As an integral part of Envara's WiND512 chipset, EN313 enables a very low-cost implementation
of wireless LAN (WLAN) Network Interface Cards (NICs) and Access Points (APs).
EN313 is compatible with the 802.11g international wireless standard.

Key Features

  • Operates within 2.412~2.484 GHz frequencies – supporting 802.11h/g/j requirements
  • Reduced BOM & small footprint
On-chip VCOs, synthesizer, LNAs
Envara's patented Enhanced Zero IF (EZ-IF) architecture enables simpler integration
and lower cost implementation by not requiring external IF or baseband filters
