2 System Architecture
Jackson Peak1 and Canyon Peak with Bluetooth contain a single chip for Wi-Fi+Bluetooth,
including Wi-Fi MAC and PHY as well as Bluetooth MAC and PHY. Jackson Peak 2 is a 2 chip
solution. All the modules are HMC (Half Mini Card) format. Marble Peak and Canyon Peak are
both WiFi only solutions.
2.1 Frequency Stability
The 40MHz clock has 20ppm maximum frequency stability. It is multiplied up to generate the
transmit signal. Hence when operating in the b/g band at 2.412GHz we will have an error of
2.412GHz*20ppm when tuned to the lower channel and at the extreme it will be 2.484GHz *
20ppm when tuned to the upper channel. When operating in the band, it has a frequency error
of the operation frequency *20ppm.
2.2 Data Transmission
Data transmission is always initiated by software, which is then passed down through the
MAC, through the digital and analog baseband, and finally to the RF chip. Several special
packets (ACKs, CTS, PS Poll, etc.) are initiated by the MAC. These are the only ways the digital
baseband portion will turn on the RF transmitter, which it then turns off at the end of the
packet. Therefore, the transmitter
is being transmitted.

requirements and design.
