Cascading Multiple EP196s
internal cascade circuitry has been included. This circuitry
allows for the cascading of multiple EP196s without the
need for any external gating. Furthermore, this capability
requires only one more address line per added E196.
Obviously, cascading multiple programmable delay chips
will result in a larger programmable range; however, this
increase is at the expense of a longer minimum delay.
two EP196s. As can be seen, this scheme can easily be

To increase the programmable range of the EP196,

expanded for larger EP196 chains. The D10 input of the
EP196 is the cascade control pin and when assert
HIGH switches output pin CASCADE to HIGH and
pin CASCADE to LOW. With the interconnect scheme of
Figure 6 when D10 is asserted, it signals the need for a larger
programmable range than is achievable with a single device.
The A11 address can be added to generate a cascade output
for the next EP196. For a 2−device configuration, A11 is not
required.
