CBTU02044HEJ

CBTU02044HEJ 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.

• Optimized high-speed signal integrity, minimize crosstalk to meet stringent PCIe4.0 requirement
• Differential input voltage VID <lt/>1.6V, intra-pair skew <lt/>4ps
• CMOS SEL and XSD pins, back current protection on all I/O pins of these switches
• All channels support rail-to-rail input voltage (up to 2.4V)
• ESD: 2000 V HBM; 1000 V CDM
• Supply voltage range from 1.62 to 3.63V (3.3V supply option)
• Supply current is 3μA typ (XSD = HIGH (disable))
• Enable time is 90μs max (XSD going LOW to channel specified operating characteristics)
• Reconfiguration time is 18ms typ (SEL state changes)
• HUQFN16 package, ambient temperature range from -40°C to +85°C
