1.5 Consumer and computer interface circuits  (Page 2/2)

Examples include:

XIO2001 – PCIe to PCI bridge: http://www.ti.com/product/xio2001 .

TUSB9261 – USB 3.0 to SATA bridge: http://www.ti.com/product/tusb9261 .

Host or device controller devices

These types of controller devices provide more functionality than bridging devices and allow designers to implement a complete interface on either a host PC device or a peripheral device.

Examples include:

TUSB7320 – USB 3.0 xHCI host controller: http://www.ti.com/product/tusb7320 .

XIO2213B – 1394b OHCI host controller: http://www.ti.com/product/xio2213b .

TUSB3210 – USB GPIO device controller: http://www.ti.com/product/tusb3210 .

PCI1510 – PCI cardbus controller: http://www.ti.com/product/pci1510 .

Parallel to serial interface and serial to parallel interface converters

This type of device converts a parallel interface (normally single-ended CMOS) to a serial interface (normally a differential low-voltage signal) and vice versa. These devices help designers quickly transition a system using a legacy parallel interface to a newer serial interface.

Here are several examples:

SN75LVDS83C – 28 parallel in, four serial out FlatLink™ transmitter: http://www.ti.com/product/sn75lvds83c .

SN75LVDS86A – three serial in, 21 parallel out FlatLink™ receiver: http://www.ti.com/product/sn75lvds86a .

TFP410 – 24 parallel in, three serial out PanelBus DVI transmitter: http://www.ti.com/product/tfp410 .

TFP401A – three serial in, 48 parallel out PanelBus DVI receiver: http://www.ti.com/product/tfp401a .

SN65LVDS301 – 27 parallel in, three serial out FlatLink3G transmitter: http://www.ti.com/product/sn65lvds301 .

SN65LVDS302 – three serial in, 27 parallel out FlatLink3G receiver: http://www.ti.com/product/sn65lvds302 .

Voltage-level translators

Level translator devices provide a way for system designers to convert electrical signals from one interface standard to another.

Examples include:

SN75DP139 – dual-mode DisplayPort to DVI/HDMI level translator (3.4 Gbps): http://www.ti.com/product/sn75dp139 .

SN75DP129 – dual-mode DisplayPort to DVI/HDMI level translator (2.5 Gbps): http://www.ti.com/product/sn75dp129 .

Switching or muxing devices

These types of devices allow multiple input sources to switch in or switch out to multiple output devices. Two types of switching devices – active and passive switches – allow designers to select the appropriate device based on cost-constraint and performance requirements.

Active switch examples include:

SN75DP126 – one input to two output DisplayPort switch: http://www.ti.com/product/sn75dp126 .

TMDS442 – four input to two output DVI/HDMI switch: http://www.ti.com/product/tmds442 .

TMDS361B – three input to one output DVI/HDMI switch: http://www.ti.com/product/tmds442 .

Passive switch examples include:

HD3SS212 – 5.4-Gbps DisplayPort 1.2 two input to one output switch: http://www.ti.com/product/hd3ss212 .

HD3SS3412 – 12-Gbps PCIe Gen III/USB 3/DisplayPort four-channel 2:1 switch: http://www.ti.com/product/hd3ss3412 .

Hub or fanout devices

These types of devices allow system designers to increase the number of interface ports for a particular interface standard in a cost-efficient way without suffering performance degradation.

Examples include:

TUSB8040A – one upstream to four downstream USB 3.0 SuperSpeed hub: http://www.ti.com/product/tusb8040a .

TUSB2046B – One upstream to four downstream USB FullSpeed hub: http://www.ti.com/product/tusb2046b .

XIO3130 – one upstream to three downstream PCI Express x1 switch: http://www.ti.com/product/xio3130 .

Signal-conditioning devices

These types of devices allow system designers to compensate for signal loss caused by long traces or cable length and improve signal quality at the connector or receiving device end to meet specification requirements.

Examples include:

SN65LVPE502A – dual-channel USB 3.0 redriver/equalizer: http://www.ti.com/product/sn65lvpe502a .

SN75DP130 – DisplayPort redriver with link training: http://www.ti.com/product/sn75dp130 .

Industrial standards defining digital interfaces

There are overwhelming advantages to implement an industrial standard rather than a proprietary interface to ensure wide adoption, economy of scale for low cost, interoperability and robustness, and consumer awareness.

How to read a data sheet

Features. This section generally describes the type of industrial standard supported, data rate, number of channels, number of pins and package type.

Functional description or theory of operations. This section describes the function of the device in more detail and includes block diagrams, a typical application circuit, timing diagrams and register tables (where applicable).

Terminal description. This section lists the device pin terminal list, with descriptions of what the pin does.

Electrical characteristics. This section specifies the electrical signal levels of each pin as well as the power-supply requirements.

Package mechanicals. This section specifies the mechanical dimensions of the device package to help designers lay out the printed circuit board.
