Block Diagram: FVG318 Block Diagram as below:$

1. CPU, U3, AR2316 Single Chip MAC/ Baseband/ Radio/ Processor for 2.4GHz
Wireless LANs.
The Atheros AR2316 integrated the MAC/ baseband/ radio and processor into a
single chip for wireless access point and router applications. It includes a 2.4GHz
radio, MIPS 4000 processor, 802.11 MAC/ baseband processor, 802.3 Ethernet
MAC and MII interface, SDRAM controller, external memory interface for Flash,
ROM, or UART, GPIOs, LED controls.
The AR2316 implements an 802.11 MAC/ baseband processor supporting all IEEE
802.11g data rates (1 to 54 Mbps) and all IEEE 802.11b complementary key coding
(CCK) data rates (1 to 11 Mbps). In Atheros super GTM mode, AR2316 supports
data rates up to 108 Mbps. Additional features include forward error correction
coding at rates for 1/2, 2/3, and 3/4, signal detection, automatic gain control,
frequency offset estimation, symbol timing, channel estimation, error recovery,
enhanced security, and quality of service (QoS).The AR2316 performs receive and
transmit filtering for IEEE 802.3 and 802.11 network.

2. 2.4GHz – 2.5GHz Power Amplifier, U4, GP1214
GP1214 is a low cost and high performance power amplifier IC based on the highly
reliable InGaP/GaAs HBT technology. With a 3x3 mm2 16-pin LCC package,
GP1214 can be easily configured for high power/high efficiency application with
superb power added efficiency while operating over the 2.4~2.5 GHz frequency band.
It typically provides 30dB gain with 22% power added efficiency @ Pout= 22 dBm
for 802.11g and 27% power added efficiency @ Pout= 24 dBm for 802.11b. GP1214
has excellent linearity, typically <4% added EVM up to 20 dBm output power which
is essential for 54 Mbps 802.11g operation while meeting 802.11g spectrum mask at
23 dBm. GP1214 also has wide-range (>25dB) temperature stable (~1dB over 80°C)
single-ended/differential power detectors which lower users’ cost on power control.
The power amplifier IC also features easy board level usage along with high speed
power up/down control. Ultra-low reference current (total Iref<4mA) makes GP1214
controllable by on/off switching signal directly from baseband chip. These features
coupled with low operating current make GP1214 ideal for the final stage power
amplification in battery powered 802.11g/b WLAN transmitter applications.

Fast Ethernet Switch with 10Base-T/100Base-TX(U1,U9)
The Marvell 88E6060 is a single chip integration of a complete 6-port Fast Ethernet
switch with support for a CPU connection. It contains five 10BASE-T/100BASE-TX
transceivers(PHYs),two that can be used to set-port 100 BASE-FX; six independent
Fast Ethernet media access controllers(MACs),a high-speed nonblocking switch
fabric, a high-performance address lookup engine, and a 1/2 Mbit frame buffer
memory. It is designed for cost-sensitive low port count switch systems and firewall
routers.

The Marvell 88E6060 is designed to work in all environments. True Plug-n-Play is
supported with Auto Cross Over, Auto Polarity and Auto Negotiation in both the
PHYs, along with bridge loop prevention(using Port States implementing Spanning
Tree support).

The shared memory-based switch fabric uses the latest Marvell switch architecture
that provides non-blocking switching performance in all traffic environments.
Back-pressure and pause-frame-based flow control schemes are included to support
zero packet loss under temporary traffic congestion. The lookup engine allows for up
to 1024 active nodes to be connected with the switch.

The 6th port “always on” RMII/MII/SNI interface supports a direct connection to
Management or Router CPUs with integrated MACs. It can be configured in either
RMII mode, MII-PHY or MII-MAC mode or SNI mode. These interfaces along with
BPDU handling, programmable per port VLAN configurations, and Port States,
support Spanning Tree and truly isolated WAN vs. LAN firewall applications.
