CBTL04GP043
Dual 2 x 2 differential channel crossbar switch
Rev. 1 — 8 September 2014
Product brief
1. General description
The CBTL04GP043 is a high-performance 4-channel bidirectional crossbar switch
supporting both high speed and large swing signals. The high-speed differential signals
include PCIe-Gen3, USB3 and DisplayPort. The large swing signals include UART,
USB 2.0 and HDMI 1.4 signals.
This chip can be configured as pair straight through or cross to the output ports through
the CROSS signal. It can be placed under Low-power mode using the XSDN pin.
This crossbar switch supports wide common-mode voltage range from 0 V to V
DD
on all
input and output ports.
CBTL04GP043 is available in 2.00 mm
4.00 mm
0.5 mm XFBGA28 package with
0.5 mm pitch.
2. Features and benefits
4-channel, bidirectional crossbar switch
The input of the CROSS pin
CROSS is LOW for connecting input and output ports straight through
CROSS is HIGH for crossbar connection between input and output ports
When XSDN is LOW, the switch is in low-power sleep mode
