The GX79474 is a low-power, high-performance, quad-channel linear driver chip designed for 800Gbps and beyond optical integrated transmitter small form factor (SFF) modules for metro and long-haul applications.

The GX79474 integrates analog control and digital (through an SPI interface) control circuitry for precise, independent driving level control and monitoring. Each driver channel has a 100Ω differential AC-coupled input and 60Ω differential interface with an open-collector type output stage, suitable for InP-based and silicon photonics-based Mach-Zehnder modulators.

GX79474 Linear Differential I/O Driver Block Diagram
  • >70GHz 3dB E/O bandwidth
  • >10dB dynamic range of gain control
  • <2.0W (typical) power consumption for 2.0Vppd output voltage swing
  • AC-coupled 100Ω differential input
  • Open-collector configuration output stage that can drive DC-coupled 60Ω differential
  • Ultra-low inter-channel crosstalk
  • Up to 15dB of peaking to compensate for package and modulator losses
  • Precise analog and digital monitoring and control of gain and output voltage swing
  • <1MHz low-frequency cutoff
  • Optical Internetworking Forum (OIF)-compliant serial peripheral interface (SPI) for programmability

应用

  • 800G and beyond advanced multi-level QAM modulation systems
  • High-bandwidth small form factor optical integrated modules

    Parametric Table tips

    Tips for Using This Parametric Table:

    • Hide Filters button in header: Collapse or expands filters
    • Column sort buttons in header: Sort Column alphabetically / numerically descending or ascending
    • Reset button in header: Reset all filters to the page default
    • Full Screen button in header: Expand the table to full screen view (user must close out of full screen before they can interact with rest of page)
    • Export button in header: Export the filtered results of the table to an Excel document
    • Filter parts search bar in header: Type to filter table results by part number
    • Hide column button in column headers: Select to hide columns in table
    • AND / OR toggle switches in header: Toggles the logic of this particular filter to be “AND” or “OR” logic for filtering results
    • Multiselect checkboxes at beginning of each row in table: Select these checkboxes to compare products against each other
    • Document icon next to product name in row: View the featured document for this product
    • Chip icon next to the right of the document icon in row: View the block diagram for this product
    • Cart icon to the right of the chip icon: Indicates that samples are available for this product
