Wifi Adapter
Introduction
The Wireless Network Adapter is a dual-band (2.4/5GHz) 802.11a/b/g interface for the Xbox 360.
This is a standard USB 2.0 device, and although it is designed to clamp onto the back of the console, it works when plugged into a standard USB port, given your operating system has accompanying device drivers. See below.

Marvell MVPG16
MG16R 00A2R 521AC
The MVPG16 is an integrated DC-DC synchronous step-down switching regulator. Input voltage ranges from 3.0V-5.5V. Output voltage ranges from 0.72V-3.63V and is user-programmable via a single external resistor.
There's no readily available datasheet for this particular IC, however, one for it's modular MDx-G16 counterpart is, for download. There's a two-page brochure as well, but is rather lacking in the more technical details.

The 88W8388 is an 802.11a/b/g WLAN SoC from Marvell. Embedded are an ARM946E-S core (as per the ARM Networking.pdf Networking brochure) and on-chip memory. Together with an integrated TCP/IP stack, this allows for off-loading the host processor of protocol processing. This SoC is targeted at small-footprint devices, eg. cellular/VoIP phones, PDAs, video game consoles, etc.
The 88W8388 is 88W88305-derived, as indicated below (table reproduced from http://www.clv.macnica.co.jp/product/marvell/sub1.html):
