Text with a Mosaic Background
We are going to create mosaic background for your text like this:
Step 1
Create a new document. Make it large enough for your text, i made it 300x200 pixel.
Type your text in a color of your choice.

Step 2
Now duplicate your text layer, set the copy's visibility to invisible and select the original text layer.
Use Filter --> Pixelate --> Mosaic
I chose to make the cell size 19 square, you might want to make them bigger or smaller.

Step 3
Apply Filter --> Sharpen --> Sharpen Edges a few times (3-5)
You will get something like this:

Step 4
Make your duplicated text layer visible again.
Color the text white.
Right click the layer --> Blending options
Apply these settings for stroke (use your original text color):

You're done, you should end up with an image similar to this:
