Hello,
If you look at the datasheet, you will see that this device is focussed on DDR2/DDR3 memory design.
As this type of memory is surpassed by newer standards, these analyzer have become obsolete in the industry.
These high-end devices are specifically created for design and product(ion) verification and are a brilliant piece of equipment.
That said, it now is 'just' a generic logic analyzer, a clunky and noisy unit, big on ones home lab desk.
Still very usefull with high speed logic design though.
Smaller, although less high speed, PC / USB driven analyzer are very affordable.
And feature all kinds of serial decoding whigh this TLA6402 does not support (as far i can tell from the datasheet)
Compared to the vast community of embedded cpu engineers and hobbyists, logic designer numbers are small.....
Thus demand will be limited.
