Introduction

DG2735ADN-T1-GE4 is an analog switch, multiplexer and demultiplexer designed to switch between high speed analog signals. With higher performance frequency range and on resistance set, it can operate in various interface applications. This device operates between -40 C and 85 C and is made of CMOS technology.

Application Field

DG2735ADN-T1-GE4 is suitable for wide range of interface applications that require protection and high speed switching. It can be used in data converters and other analog switching applications. It is applicable in high speed USB interfaces, HDMI interfaces, serial data interfaces or Camera Interfaces.Its application fields inculdes,

• High-speed USB 2.0, 3.0, 2.4 and 2.6 interfaces.
• High-speed HDMI switching, sending and receiving applications.
• ADC and DAC switching applications, for precision data transferring.
• High-speed serial data interfaces, such as LVDS, SDI and LVDS.
• High-speed Camera Interface. It can be used as a transmitting interface between the image sensor and the buffer.

Working Principle

DG2735ADN-T1-GE4 is designed to switch between high speed analog signals. It has on-resistance flatness 0.5 dB down to its rated frequency range of up to 35 MHz. The device also has low leakage current and on-resistance that are optimized for the high speed applications. In order to allow the transfer of data without any distortion, the device is designed with clock resonators and transformers that reduce power loss and EMI. It also has two analog switches that are placed parallel to one switch with a small delay. This prevents buffer overflow and output dead-time. The device is also implemented with a unique voltage monitor (VMON) circuit which powers the analog switch only at appropriate voltage levels effectively avoiding the clamping of the high-speed data transmitted during switching operations.

Conclusion

DG2735ADN-T1-GE4 is an analog switch, multiplexer and demultiplexer designed to switch between high speed analog signals. It has higher performance frequency range, on resistance set and low leakage current that are optimized for the high speed applications such as USB 2.0/ 3.0 interface, HDMI switching, serial data interfaces, and camera interfaces. It also has a unique voltage monitor (VMON) circuit which powers the analog switch only at appropriate voltage levels effectively avoiding the clamping of the high-speed data transmitted during switching operations.
