The MC100EP196 ECL programmable delay chip from ON Semiconductor operates at frequencies >1.2GHz and offers delay timings between 2.2ns to 12.2ns in 10ps units, making it suitable for use in high-frequency clock management applications.

Available in a 32-pin LQFP casing, the IC features a secondary tuning input for clock deskew in networking systems, pattern generation, and pulse and data formatting in test and instrumentation equipment. A fine tune input feature allows the device to deliver supplementary delay programmability between 0ps and 60ps and eliminates the need to re-spin, re-assemble, and re-test circuit boards if the timing signals do not match.

Aside from ECL, the MC100EP196 also accepts CMOS and TTL signals allowing system designers to directly program the device via a microcontroller. It is also compatible with both positively- and negatively-referenced 3V to 3.6V system supplies in PECL or NECL mode, respectively.
