CBTL04083ABS,518

The CBTL04083ABS,518 from NXP Semiconductors is a versatile 4-differential channel, 2:1 multiplexer/demultiplexer switch engineered for high-speed serial interface applications, particularly PCI Express Generation 3 (PCIe Gen3). This device enables the switching of four differential signals to one of two locations, facilitating expansion of existing high-speed ports with minimal power consumption.

Key electrical characteristics include support for 8.0 Gbit/s PCIe Gen3 speeds, with a high bandwidth of 8.3 GHz (-3 dB) for the CBTL04083A variant. It boasts low intra-pair skew of 5 ps typical and low inter-pair skew of 35 ps maximum, ensuring signal integrity. The switch also features low crosstalk (-29 dB at 4 GHz), low insertion loss (-0.5 dB at 100 MHz, -1.3 dB at 4 GHz), and low off-state isolation (-20 dB at 4 GHz).

The operating voltage range is 3.3 V ± 10%. The device is housed in a 42-HVQFN package with surface mount mounting type. It is suitable for applications requiring routing of high-speed differential signals with low signal attenuation, such as PCIe Gen3, DisplayPort 1.2, USB 3.0, and SATA 6 Gbit/s.

Additional features include dual shutdown pins for independent channel control to minimize power consumption and ESD tolerance of 2000 V HBM and 1000 V CDM. The operating temperature range is -40°C to +85°C.
