EDGE HIGH-PERFORMANCE PRODUCTS
Application Information
Edge142
Comparator Return Path
The Edge142 is designed specifically to buffer multiplex,
and deskew multiple comparator paths from multiple test
heads to the timing generators located back in the tester
mainframe. The Edge142 provides a one IC solution
between the pin electronics and the error strobing
circuitry. Most importantly, the Edge142 performs all of
the timing deskew functions, thus removing the burden
of timing compensation from the error section. By
performing the calibration with the Edge142, there may
be some improvement in the edge to edge retrigger time
inside the timing generator.
