Time Interval Analyzer

There is one type of TIA available as follows:

• High performance TIA  Code name: TIA

• General purpose TIA  Code name: TIA

These TIAs provide the same functions. Some specifica-

tions are different between these TIAs. For specifications,

see Table 42 and Table 43.

TIA Overview

The Time Interval Analyzer (TIA) performs time measure-

ments for digital or analog signals, and stores the results.

Signals can be input to one TIA module through two input

lines as follows:

• Channel 1 (Start channel at propagation delay

measurement)

• Channel 2 (Stop channel at propagation delay measure-

ment)

The input signals to these input channels are converted to

digital signals with the specified threshold levels at the

front end of the input channels.

The TIA can perform the following four kinds of interval

measurements available:

• Pulse width on either channel 1 (PW)

• Pulse period on either channel 1 (PER)

• Frequency of a signal on either channel 1 (FREQ)

• Propagation delay between edges on dual channels
