Device Structure

The IC integrates a 3:3 multiplexer circuit with support for differential signaling. It is designed for surface mounting onto PCBs and housed in a 28-TSSOP package for compact, high-density layouts. It does not use PLL circuitry and is not verified as DiGi-Electronics programmable.

Performance Characteristics

Reliable operation at industrial temperature ranges from -40°C to 85°C. Supports high-speed differential interface standards (CML, LVPECL) for both input and output, ensuring low jitter and improved signal integrity for mission-critical timing and link replication in communication systems. The supply voltage range is tightly controlled, supporting demanding high-speed applications.

Application Environments

Best used in Fibre Channel switches, Gigabit Ethernet routers, HDTV systems, storage networks (SATA), and anywhere reliable and precise timing, link replication, or multiplexing is required. The device suits harsh industrial environments due to its wide temperature range and robust construction.

Selection Guidelines

Choose this IC when you need stable and synchronized replication or multiplexing of timing/data links in high-speed networking and broadcast systems. Verify voltage supply compatibility (3.135V to 3.465V) and ensure your PCB layout is suited for differential CML/LVPECL inputs and LVPECL outputs. Check if 3:3 input/output ratio fits your design.

Usage Considerations

Handle with ESD protection and maintain proper storage to avoid moisture-induced failure, adhering to MSL 3 rules. Use only in surface-mount compatible processes. Match impedance for differential pairs to minimize reflections and signal loss. Keep operating voltage and temperature within specified ranges for best performance.
