MC100E195FN

The MC100E195FN from ON Semiconductor is a versatile Programmable Delay Chip (PDC) primarily used for clock de-skewing and precise timing adjustments in electronic systems. It provides a variable delay for differential ECL input transitions, offering a wide operating frequency range of over 1.0 GHz with a substantial output swing.

This device features a digitally selectable delay resolution of approximately 20 ps, with a worst-case delay range of 2.0 ns. The delay is programmed via seven address inputs (D[0:6]) which are latched on-chip by the latch enable (LEN) control. An eighth input (D7) allows for cascading multiple PDCs to extend the programmable delay range without requiring external gating logic.

The MC100E195FN operates with a PECL mode voltage range of 4.2V to 5.7V (VCC) with VEE at 0V, or NECL mode with VCC at 0V and VEE from -4.2V to -5.7V. It includes internal input pulldown resistors and ESD protection exceeding 2 KV HBM. The chip is housed in a 28-PLCC (J-Lead) surface mount package.

Designed for applications requiring accurate system clock timing, the MC100E195FN is suitable for high-frequency digital circuits where precise delay control is critical. Its programmability from digital inputs simplifies system integration and calibration.
