DESCRIPTION
The SY100EP196V is a programmable delay line, varying the time a logic signal takes to traverse from IN to Q. This delay can vary from about 2.2ns to about 12.2ns. The input can be PECL, LVPECL, NECL, or LVNECL.
The delay varies in discrete steps based on a control word presented to SY100EP196V. The 10-bit width of this latched control register allows for delay increments of approximately 10ps. In addition, delay may be varied continuously in about a 30ps range by setting the voltage at the FTUNE pin.
An eleventh control bit allows the cascading of multiple SY100EP196V devices, for a wider delay range. Each additional SY100EP196V effectively doubles the delay range available.
