CBTU02044
Overview
CBTU02044 is a high-speed differential 1-to-2 switching chip optimized to interface with PCIe4.0 for server and client applications. This high performance switch chip could be used for other high-speed interfaces such as PCIe-Gen4, MIPI, DP1.4, and DDR.
- Optimized high-speed signal integrity
- Minimize crosstalk to meet stringent PCIe4.0 requirement
- Two-differential channels 1-to-2 switch/2-to-1 mux - Low insertion loss (typ): 0.56 dB at 100 MHz; 1.1 dB at 5 GHz; 1.5 dB at 8 GHz - Low off-state isolation: -70 dB at 100 MHz, -23 dB at 5 GHz, -18 dB at 8 GHz - Low return loss (typ): 21 dB at 2.5 GHz; 18 dB at 5 GHz; 15 dB at 8 GHz - Low ON-state resistance: 10 Ω (typ) - 3 dB bandwidth (typ): 17 GHz (typ) - DDNEXT < -50 dB @ 8 GHz - DDFEXT < -48 dB @ 8 GHz - VIC common mode input voltage VIC: 0 V to 2 V - Differential input voltage VID <1.6 V - Intra-pair skew <4 ps
- VDD power supply voltage range: 1.62 V to 3.63 V
- Low current consumption: - For active mode = 200 μA (typ) - For power-saving = 3 μA (typ)
- CMOS SEL and XSD pins
