CBTL04082BBS,518

Overview

The CBTL04082BBS,518 is a bidirectional multiplexer/demultiplexer switch designed for PCI Express Generation 2 applications. It manages four differential channels, routing signals between two selectable locations with negligible attenuation and minimized skew. The device operates on a 3.3 V supply (±10%) and supports high-speed signal switching up to 5 Gbit/s. Key electrical parameters include a −3 dB bandwidth of 6 GHz, insertion loss of −0.5 dB at 100 MHz and −1.2 dB at 2.5 GHz, and low intra-pair skew of 5 ps typical. It features dual shutdown pins for independent channel control, standby current under 1 μA, and ESD tolerance of 8 kV HBM.

Procurement Notes

Verify the ordering code matches the specific package variant required for your design. Confirm that the HVQFN42 footprint aligns with your PCB layout constraints. Ensure thermal pad soldering procedures are followed to maintain electrical grounding and heat dissipation. Check the latest datasheet revision for any updates to recommended operating conditions or pin configurations before finalizing procurement.

Selection Notes

Select this component when designing systems requiring low-loss switching for four differential pairs in PCIe Gen2 environments. Consider the CBTL04082ABS if your layout requires input/output pins on opposite sides of the package. Verify that the 3.3 V supply voltage range meets your system's power requirements. Evaluate the shutdown functionality needs to determine if independent channel control is necessary for power optimization.
