CBTL04083A/CBTL04083B 3.3 V, 4 differential channel, 2 : 1 multiplexer/demultiplexer switch for PCI Express Gen3 Rev. 4.1 27 July 2020 Product data sheet 1 General description CBTL04083A/B is a 4 differential channel, 2-to-1 multiplexer/demultiplexer switch for PCI Express Generation 3 (Gen3) applications. The CBTL04083A/B can switch four differential signals to one of two locations. Using a unique design technique, NXP has minimized the impedance of the switch such that the attenuation observed through the switch is negligible, and also minimized the channel-to-channel skew as well as channel- to-channel crosstalk, as required by the high-speed serial interface. CBTL04083A/B allows expansion of existing high speed ports for extremely low power. The device s pin out are optimized to match different application layouts. CBTL04083A has input and output pins on the opposite of the package, and is suitable for edge connector(s) with different signal sources on the motherboard. CBTL04083B has outputs on both sides of the package, and the device can be placed between two connectors to multiplex differential signals from a controller. Please refer to Section 8 for layout examples. 2 Features and benefits 4 differential channel, 2 : 1 multiplexer/demultiplexer High-speed signal switching for 8.0 Gbit/s PCIe Gen3 speed Low intra-pair skew: 5 ps typical Low inter-pair skew: 35 ps maximum High bandwidth: -3 dB at 8.3 GHz for CBTL04083A -3 dB at 8.0 GHz for CBTL04083B Low crosstalk: -29 dB at 4 GHz Low insertion loss -0.5 dB at 100 MHz -1.3 dB at 4 GHz Low off-state isolation: -20 dB at 4 GHz Low return loss: -14 dB at 4 GHz V operating range: 3.3 V 10 % DD Dual shutdown pins for channel 0/1 and 2/3 independently to minimize power consumption ESD tolerance: 2000 V HBM 1000 V CDM HVQFN42 packageNXP Semiconductors CBTL04083A/CBTL04083B 3.3 V, 4 differential channel, 2 : 1 multiplexer/demultiplexer switch for PCI Express Gen3 3 Applications Routing of high-speed differential signals with low signal attenuation PCIe Gen3 DisplayPort 1.2 USB 3.0 SATA 6 Gbit/s 4 Ordering information Table 1.Ordering information Type number Topside Package marking Name Description Version CBTL04083ABS L04083A HVQFN42 plastic thermal enhanced very thin quad flat package no SOT1144-1 1 leads 42 terminals body 3.5 9 0.85 mm CBTL04083BBS L04083B HVQFN42 plastic thermal enhanced very thin quad flat package no SOT1144-1 1 leads 42 terminals body 3.5 9 0.85 mm 1 Total height after printed-circuit board mounting = 1.0 mm maximum. 4.1 Ordering options Table 2.Ordering options Type number Orderable part Package Packing method Minimum order Temperature number quantity 1 CBTL04083ABS CBTL04083ABS,518 HVQFN42 REEL 13 Q1/T1 4000 T = -40 C to +85 C amb DP CBTL04083ABS,558 HVQFN42 REEL 13 Q1/T1 4000 T = -40 C to +85 C amb DP 2 CBTL04083BBS CBTL04083BBS,518 HVQFN42 REEL 13 Q1/T1 4000 T = -40 C to +85 C amb DP CBTL04083BBS,558 HVQFN42 REEL 13 Q1/T1 4000 T = -40 C to +85 C amb DP 1 CBTL04083ABS is available in tape and reel formats with different tape widths 16 mm and 24 mm: For 16 mm tape width, order CBTL04083ABS 9352 941 24518 518 indicates 16 mm wide carrier tape).
