It accepts a 4.2 GHz maximum count rate, making it suitable for PLL feedback dividers, SERDES reference paths, and RF/IF clock trees in telecom infrastructure, test equipment, and high-speed data converters. The part operates from a 3.3 V to 5 V supply, bridging legacy 5 V ECL systems and modern 3.3 V logic families. The asynchronous reset (active-low, per the 100EL convention) clears the divider immediately, independent of the clock edge — useful for deterministic power-up states or gated reset sequences. The device triggers on both positive and negative clock edges, which is typical for ECL/PECL dividers and simplifies interfacing with differential clock sources (LVPECL, CML). The asynchronous reset is a glitch-sensitive line — if the reset input is left floating or driven by a slow-edge signal, the divider may exhibit metastable behavior at power-up. In practice, tie the reset to a clean logic-high through a pull-up resistor if unused, or sequence it from a supervisory IC that holds reset during supply ramp. The 3.3 V to 5 V supply range means the same part can be used in both 3.3 V PECL and 5 V ECL environments, but the input thresholds scale with VCC — verify the logic levels of the driving source against the datasheet's VOH/VOL tables for your supply voltage. ## Sourcing and lifecycle — what to expect Microchip continues to manufacture this series, so no last-time-buy or end-of-life risk is currently flagged.","metaTitle":"SY100EL33LZG-TR Divide-by-4 Prescaler, 4.2 GHz, 8-SOIC","metaDescription":"Microchip 100EL series divide-by-4 prescaler, 4.2 GHz count rate, 3.3 V to 5 V supply, asynchronous reset, -40°C to 85°C, 8-SOIC.
