CBTL05024BS中文资料High performance multiplexer/demultiplexer switch for Thunderbolt applications数据手册恩XP规格书

描述 Description

The CBTL05024 is a multiplexer/demultiplexer switch chip optimized to interface theThunderbolt/MiniDP connector with Thunderbolt systems. It supports 10.3125 Gbit/sThunderbolt or DisplayPort v1.2 channels.
The TB MUX is a 3 : 1 switch that selects between Thunderbolt data path andDisplayPort v1.2 side-band signals — either DDC or AUX.
The DP MUX is a 2 : 1 switch that selects between DP ML (DisplayPort Main Link) andLS TX/RX signals. Both LSTX and LSRX are the side-band signals for Thunderboltchannel.
This chip also includes HPD and CA_DET buffers for HPD_IN and CA_DET controlsignals.
CBTL05024 is powered by a 3.3 V supply and it is available in a 3 mm  3 mm HVQFN24package with 0.4 mm pitch.

特性 Features

TB MUX 3 : 1 switch
• This 3 : 1 switch is implemented by two cascaded 2 : 1 switches
• The first 2 : 1 10G MUX is controlled by TB_ENA, AUXIO_EN and DP_PD pins
•The second 2 : 1 AUX MUX is controlled by CA_DET signal multiplexing of the720 Mbit/s Differential FAUX (or 1 Mbit/s AUX) and DDC (Direct Display Control)signals
• When CA_DET is HIGH, DDC path is selected
• Differential TB channel
