startKIT Hardware Manual
11 24MHz Crystal Oscillator
The startKIT board is clocked at 24MHz by a crystal oscillator. Tile 1 is clocked at
500 MIPS, and the I/O ports are 100MHz. The debugger generates an additional
25MHz clock for the PCIe slot which can be accessed using the J6 header.

12 Power connector

startKIT requires a 5V power source input via the micro-USB cable.

13 Operating requirements

A USB 2.0 high-speed compliant cable of less than 3m in length should be used
when operating the startKIT. XMOS cannot guarantee correct operation of the
startKIT should any other cable be used.
This product is designed to be powered from a USB port only and correct operation
cannot be guaranteed if it is powered otherwise.
This product is, like most electronic equipment, sensitive to Electrostatic Discharge
(ESD) events. Users should operate the startKIT with appropriate ESD precautions
in place.
14 Dimensions
The startKIT dimensions are 94 x 50mm. The mounting holes are 2mm in diameter.
