In the market, there are four
large popular and leader companies providing most chipset for
layer 2 10/100M networking switch: Realtek & ADMtek & IC+ & Broadcom.
1. Realtek: as a main
chipset supplier in China for low networking market, Realtek chose
separated MAC/PHC chipset-making construction, RTL8316 + RTL8208 for
16port switch, and RTL8324 + RTL8208 for 24port switch, both
provide 4M DRAM and 8K MAC. Quality is not bad, and has been well
proven for long time.
2. ADMtek: acquired by
German Infoneon this year, ADM also chose separated MAC/PHC chipset
-making construction, ADM6926 +
ADM7008 for 24port switch, provide 4M DRAM and 4K MAC.
ECOM , for example, will use ADMtek chipset on 8/16/24 port switch.
3. IC+: It
is the lower cost chipset supplier in Taiwan than Realtek/ADM,
also chose separated MAC/PHC chipset -making construction, IP1726 + IP108
for 24port switch, provide only 1.5M DRAM
and 4K MAC.
The short effect is that
the chipset is easy to hot and unstable and 1.5M DRAM is not
enough for high-speed transmission. Obviously, the price is
lower , as well as the performance. This way you get
a buffer RAM of only 1.5Mb. Very short.
4. Broadcom: USA and leading
chipset supplier globally on networking swtich and higher standard
switch, it has absolute quality networking compatible and stable
transmission performance. It chose Integrated
MAC/PHC chipset -making construction, BCM5328 for
16/24port switch, provide 4M DRAM and 4K MAC. LanPro uses broadcom
chipsets for higher speed and reliabilty.
