What is the MCK clock source for the SSC (serial controller), is it the same as the CPU?

Is it possible to connect the SSC (MCK) clock to one of the generic clock generator outputs?

1) The SSC is clocked by the peripheral bus.

2) Yes, you can use an external clock routed to the clock lines of the SSC peripheral.

Thanks. I found a solution without the need for external wiring.

Another question, the LCD share a pin with the SSC, will it be disabled by default on the NGW1100 board?

No, it will depend on your board code. For the NGW100 the SSC and LCDC platform device are not added in the board code.

And the SSC is not multiplexed with the LCD, which pin are you referring to?

NGW100? By default _neither_ are enabled, the pins are left unreserved.

You must add the device registration call for what ever peripherals you want to use. The default peripherals are just

usart0
mci
macb0
macb1
spi0
usba
leds
twi

-S.

I'm using the UC3A mcu on EVK1100. The SSC pins seems to be shared with the SPI1 used by dataflash, MMC and 4*20 char LCD.

Well, stating what kind of µC and board you are using is always wise ;)

If you do not plan to use DataFlash, MMC or 4*20 char LCD, then it will be fine to use the pin for SSC. You need to remember that there are other devices hooked up on the line.
