SY100EP196V 3.3V/5V 2.5 GHz Programmable Delay Chip with Fine Tune Control Features General Description Pin-for-Pin, Plug-In Compatible with the ON The SY100EP196V is a programmable delay line, Semiconductor MC100EP196 varying the time a logic signal takes to traverse from IN to Q. This delay can vary from about 2.2 ns to about Maximum Frequency >2.5 GHz 12.2 ns. The input can be PECL, LVPECL, NECL, or Programmable Range: 2.2 ns to 12.2 ns LVNECL. 10 ps Increments The delay varies in discrete steps based on a control 30 ps Fine Tuning Range word presented to SY100EP196V. The 10-bit width of = 3.0V to PECL Mode Operating Range: V CC this latched control register allows for delay increments 5.5V with V = 0V EE of approximately 10ps. In addition, delay may be = 0V with V NECL Mode Operating Range: V CC EE varied continuously in about a 30 ps range by setting = 3.0V to 5.5V the voltage at the FTUNE pin. Open Input Default State An eleventh control bit allows the cascading of multiple Safety Clamp on Inputs SY100EP196V devices, for a wider delay range. Each A Logic High on the /EN Pin will Force Q to Logic additional SY100EP196V effectively doubles the delay Low range available. D 0:10 can Accept Either ECL, CMOS, or TTL For maximum flexibility, the control register interface Inputs accepts CMOS or TTL level signals, as well as the input V Output Reference Voltage level at the IN and /IN pins.
