ASNT5079

Overview

The ASNT5079-PQC is a broadband tunable data and clock phase shifter fabricated in SiGe technology. It provides an adjustable delay range of up to 280 ps at 13 GHz and 290 ps at 1 GHz, with absolute delay stability within ±3 ps across the 0-125°C temperature range. The device operates from DC to 17 Gbps for data or 14 GHz for clock signals, utilizing fully differential CML interfaces with internal 50 Ohm termination. Power consumption is specified at 1.6 W under a single +3.3V or -3.3V supply configuration. Output jitter is limited to 1 ps peak-to-peak, and the output buffer is linearized to minimize waveform undershoot and overshoot.

Feature Summary

• Broadband tunable phase shifting capability supporting high-speed data and clock signals
• Temperature-stabilized delay adjustment with minimal variation over industrial ranges
• Linearized output buffer designed to reduce signal distortion and improve waveform integrity

Applications

• High-speed proof-of-concept prototyping

Procurement Notes

Verify the specific ordering suffix PQC to confirm the 24-pin QFN package variant. Ensure power supply configurations match the datasheet requirements for either positive or negative voltage setups. Confirm RoHS compliance status if required by your manufacturing standards. Check lead times directly with authorized distributors as availability may vary.

Selection Notes

Select this component when precise, wide-bandwidth phase adjustment is required for differential CML signals. Consider the 24-pin QFN package constraints and thermal management needs due to the 1.6W power dissipation. Evaluate interface compatibility regarding common mode voltage levels and termination requirements for AC or DC coupling modes.
