Key Features
- 1023 programmable delay taps with 12.2 ns total range enabling fine-resolution clock deskew and timing adjustment
- Supports both PECL (VCC = 3.3 V) and NECL (VEE = -3 V to -5.5 V) supply configurations for flexible system integration
- 100E ECL family compatibility ensuring deterministic propagation delays in multi-GHz clock distribution networks
Applications
SY100EP195VTG is designed for clock deskew and phase alignment in high-speed digital backplanes, SONET/SDH equipment, and test and measurement instruments operating above 1 GHz. The 1023-step programmable delay allows software-controlled timing calibration to compensate for PCB trace length mismatches in multi-channel synchronous data paths. Its dual PECL/NECL supply compatibility and 32-pin TQFP footprint simplify integration alongside existing 100E-family ECL logic in dense multi-layer board designs.

Frequently Asked Questions
How fine is the per-step delay resolution of SY100EP195VTG and how is it calculated?
With 1023 programmable steps covering a maximum delay of 12.2 ns, each tap step of SY100EP195VTG represents approximately 11.9 ps of incremental delay. This sub-50 ps resolution supports clock deskew in systems with signal paths operating above 2.5 GHz, where timing margins are measured in tens of picoseconds.
Which supply configuration should be used for SY100EP195VTG when integrating alongside 3.3 V PECL logic?
For 3.3 V PECL integration, SY100EP195VTG operates with VCC = 3.3 V and GND = 0 V in PECL mode, matching the standard positive-supply ECL logic convention. For legacy NECL systems, VCC = 0 V and VEE = -3.0 V to -5.5 V. Both modes provide the same 1023-step, 12.2 ns programmable delay function with ECL-compatible differential I/O levels.
In a SONET OC-48 board design, what advantages does SY100EP195VTG offer over a fixed delay line for clock distribution?
Unlike a fixed delay line, SY100EP195VTG allows post-assembly calibration of clock arrival time at each board slot in a SONET OC-48 chassis. The 1023 programmable steps with approximately 11.9 ps resolution compensate for PCB trace length variations of up to 1.2 cm equivalent at 155.52 MHz OC-3 rates or sub-millimeter precision at 2.5 GHz OC-48 rates, eliminating the need for impedance-matched trace length constraints during PCB layout.
