Yukyung marshals army of IC vendors for Viliv tablet

The Viliv X70 EX 3G is a mobile Internet device and ultramobile personal computer that features a 7-inch WSVGA (1,024 x 600) touch-sensitive display from manufacturer Chunghwa. Compared with the more-typical capacitive touchscreens of competing devices, the X70's resistive technology limits capabilities and is difficult to operate.

The hardware supports 720p high-definition video and includes a global-positioning system receiver, a single-chip solution for Wi-Fi and Bluetooth, and an integrated High Speed Packet Access (HSPA) cellular-data module for 3G broadband. Video conferencing is made possible through voice-over-IP and the unit's integrated microphone and Webcam.

The X70 is one of the first tablets we've analysed to use a 32-GB solid-state drive, built by SanDisk. Most of the tablets on the market integrate more cost-effective flash for storage.

Opening up the Viliv reveals a very compact design. Yukyung mounts the SSD and the HSPA module on the main board, where a majority of the other internal devices are contained.

The Viliv is very much a "globally designed" tablet; its complement of more than 90 IC packages was sourced from more than 40 suppliers.

The main brain of the X70 is its 1.33GHz Atom Z520 processor in combination with an Intel AF82US15W graphics and memory controller hub. Samsung provides the tablet's system memory: 1 GB of K4T1G164QQ DDR2 SDRAM.

GSM/W-CDMA cellular wireless connectivity is provided by a combined transceiver, the RTR6085, from Qualcomm, which also earned a design win with the selection of its MSM6290 analogue and digital base band processor by Yukyung. Four Avago Technologies power amplifiers (ACPM-7381, ACPM-7331, ACPM-7311 and ACPM-7371) are used for the X70's W-CDMA bands. On the GSM side, the manufacturer leverages a TriQuint Semiconductor quad-band power amplifier, the TOM7M5012.

Finally, Samsung delivers the 1.3-megapixel CMOS image sensor, the S5K5AAF, used for the X70's Webcam.

Though introduced quietly before Apple thrust the tablet computer into the spotlight, the X70 stands unique among competitors because of Yukyung's choice of Windows rather than the Android, iOS (in Apple's case) or webOS (HP) platforms. That software decision might appeal to those who require a tablet more closely resembling a "true PC" in operation.

As Asus, Motorola, RIM and a host of other companies jump into the tablet game, they'll closely examine design decisions by industry pioneers such as Yukyung, assessing the impact of those decisions on the marketplace and the industry. With a market as young as tablets, innovation is the key to maintaining predicted exponential growth.

Teardowns, in the meantime, will remain a great map for identifying the direction of the industry.
