High-Speed Output Driver for Serializers

Product Specifications

Technical details and manufacturing context for High-Speed Output Driver

Definition

The High-Speed Output Driver is a critical component within a Parallel-to-Serial Converter (Serializer). It receives the serialized data stream from the serializer's core logic, amplifies it to appropriate voltage levels, and drives it onto output transmission lines (e.g., coaxial cables, PCB traces) with the necessary current and signal integrity for high-speed data transmission over distances. This driver is designed to handle multi-gigabit per second data rates, ensuring minimal rise/fall times, controlled output impedance, and low jitter to preserve signal integrity. It typically operates with a supply voltage range of 1.8–3.3 V and supports output data rates from 1 to 12.5 Gbps per lane. The output swing is adjustable between 400 and 1200 mV differential peak-to-peak, with rise/fall times of 20–80 ps (20%–80% of output swing). The differential impedance is matched to 100 Ω ±10% to align with standard transmission lines. The driver consumes 50–150 mW per lane at maximum data rate and provides an output current of 2–10 mA into a 50 Ω load. It operates over a junction temperature range of -40 to 85 °C and is packaged in a footprint area of 3–9 mm². ESD protection is rated at ±2 to ±4 kV (HBM) per IEC 61000-4-2. The driver is fabricated on a silicon substrate with copper interconnects and encapsulated in a polymer package. It is essential for applications requiring high-speed serial data transmission, such as in optical transceivers, high-speed backplanes, and data communication systems. When selecting this component, verify model-specific parameters and standards with the legal manufacturer or supplier.

Working Principle

The driver receives low-voltage differential signals (e.g., LVDS, CML) from the serializer's final multiplexing stage. It uses a differential amplifier stage to boost the signal swing. A final output stage, often using current-steering architecture, provides the necessary drive current into the characteristic impedance of the transmission line (e.g., 50 or 100 ohms). It is designed for minimal rise/fall times, controlled output impedance, and low jitter to preserve signal integrity at multi-gigabit per second data rates.
