REXT Calculation:
For Example:
NOTE:
The vendor numbers above are listed only as a guide. Substitution of devices with similar characteristics will not affect the performance of the SY604.
All devices should be as close as possible to the SY604.

REXT
REXT = (VEXT + 1.25V)/IEXT
If Tspan is around 15ns, then IEXT is around 0.6mA, (see DC Characteristic Table) and assume IEXT pin is tied
to V
CC
= 0 + 1.25V/0.6mA
= 2.08K ohm
