NEATSwitch™ STHDMI001A
High bandwidth digital HDMI/DVI switch

STHDMI001A Product Page

The NEATSwitch family portfolio has been enlarged with the introduction of the STHDMI001A. The device is a high-bandwidth, differential digital video switch able to support the industry-proven Digital Visual Interface (DVI) and the latest High Definition Multimedia Interface (HDMI) standard for digital consumer products. The STHDMI001A also provides Transition Minimized Differential Signaling (TMDS).

STHDMI001A Features and Benefits


The STHDMI001A consists of two sets of 4 differential pairs of input channels (3 for data and 1 for clock), and one set of 4 differential output channels. This switch is controlled by a single logic signal, thus allowing easy control of the switch through TV software.
High Bandwidth: up to 500MHz
Data transfer rates: up to 1.65Gbps
Low crosstalk: –40dB @ 250MHz
Low off-isolation: –36dB @ 250MHz
Low RON: 5.5Ohm(typ)
TMDS signaling

The combination of high bandwidth, low cross-talk, and low off-isolation of the STHDMI001A provides a simple-to-use, cost-effective solution for consumer electronics products. The STHDMI001A is optimal for pixel rate switching which allows excellent video signal reproduction with extremely low power consumption and propagation delay.
The high bandwidth supports superior image quality and allows overall cost reduction by replacing redundant Physical Layers (PHYs).

Single Port Digital Display Applications


The STHDMI001A switch is designed for high-end displays like TV (Digital TV, Digital CRT, LCD, PDP, DLP and RPTV), PC graphics, or monitors where switching between two or more HDMI/DVI sources to be connected to a single video display unit is required.

Dual Port HDMI/DVI MUX TV Switching


The STHDMI001A can be used in displays with a single HDMI/DVI connector to de-mux the input video signals to the main display or to the PIP
high-definition video.

STHDMI001A Lead-Free Package


This device is available in the lead-free TSSOP48 package, with a high pitch of 0.5mm. This makes it easier for PCB designers to route traces on a single-layer or double-layer Class2- or Class3-type PCB.
This enables manufacturers to take advantage of overall cost savings by using simple PCB designs and eliminating the need for building systems with two HDMI/DVI receivers. In most instances, only a single HDMI or DVI video output is required to be displayed on the TV or monitor.
