CBTU02044 - High-speed two-differential channels 1-to-2 switch

General Description

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.

Key Features

  • 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 bandw.

CBTU02044 High-speed two-differential channels 1-to-2 switch Rev. 1.2 — 21 April 2022 Product data sheet 1 General description 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. CBTU02044 also functions as a 2-to-1 MUX by selecting 1 (Port A) as output out of one of the two differential ports (either Port B or C). Pinouts are optimized for minimum number of layout layers and for achievement of very low crosstalk to meet stringent crosstalk requirements at higher data rate. CBTU02044 is a small package with optimized footprint for smaller real estate occupancy.
