CROSS REFERENCE TABLE
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.
For maximum flexibility, the control register interface
accepts CMOS or TTL level signals, as well as the input
level at the IN
± pins.
