Dual-channel XAUI to SFI Reference Design for Systems with Two or More SFP+ Optical Ports
TIDA-00234: The TIDA-00234 XAUI to SFI reference design is intended for Enterprise and Service Provider Networking applications like Ethernet Switches and Routers that implement multiple 10G Ethernet compliant Optical (SFP+) ports. This reference design features the TLK10232 device which is the most compact Dual-channel XAUI-to-SFI Transceiver with the lowest power consumption in its category. This reference design allows access to the high-speed signals (up to 10Gbps) generated by the TLK10232 via SMA connectors or an SFP+ Module via the SFP+ optical module cage. Also, featured is the CDCM6208 device that can provide extremely low-jitter Clock input to the TLK10232 in customer systems that do not have one available (or does not meet the jitter requirement of the system).
DisplayPort Video 4:1 Aggregation Reference Design
TIDA-00309: This verified reference design is a complete four channel DisplayPort aggregation and de-aggregation solution. One TLK10022 is used to aggregate four synchronous DisplayPort (DP) sources together into one 10.8 Gbps serial link. The serial data is transferred via copper or optical fiber where a second TLK10022 is used to de-aggregate and seamlessly redisplay the original video content.
Single-Phase Energy Meter Solution for Advanced Applications
TIDM-EMETER-CORTEXM3: This design features a dual-core microcontroller implementing an integrated electricity metering solution. The meter has been tested to prove 0.5% accuracy across a current dynamic range of 2000:1 by using a precision, low-noise op-amp and a programmable gain amplifier (PGA) to provide four gain stages. The metrology calculations are performed independently of the MCUs' integrated cores, leaving both MCUs available for other applications, including Power Line Communications(PLC). Developers will benefit from this design by taking advantage of both the M3 and C28x MCUs to provide the e-meter host applications and PLC communications.
Power-optimized 16-bit 1MSPS Data Acquisition Block for Lowest Distortion and Noise Reference Design
TIPD149: This TI Verified Design is the realization of a high precision, 16-bit 1MSPS data acquisition system suitable for applications such as digital audio that require front-ends with very low distortion and noise. The circuit uses a high performance Successive Approximation Register Analog to Digital Converter (SAR ADC) and has been optimized to provide superior dynamic performance, without excessive power consumption.
Dual-Wideband RF-to-Digital Receiver Design
TIDA-00073: The TSW1265EVM is an example design of a wideband RF to digital dual receiver solution capable of digitizing up to 125MHz of spectrum. The system provides a reference on how to use the ADS4249, LMH6521, LMK0480x, and a dual mixer to achieve this. This reference EVEM coupled with a capture card such as the TSW1400 can be used to capture and analyze narrow band and wideband signals. Instructions are provided on how to change the LO and IF frequencies for different application needs. The TIDA-00073 was implemented with hardware from the TSW1265EVM.
Efficient, LDO-free Power Supply for a 12-bit 500-MSPS ADC Reference Design - PMP9767.2 - TI Tool Folder
PMP9767: The electrical performance of data converters depends on the cleanliness of their supply voltages. Linear regulators (LDOs) are commonly used but have low efficiency and high power loss, which is unsuitable for portable applications. Using a switch mode power supply (SMPS) instead, such as the TPS62231 and TPS62237, is a cost-effective and efficient power supply solution. Such a solution does not degrade the performance of the 12-bit ADS540x family of analog to digital converters (ADCs) and does not waste excessive power. The test report shows the Signal to Noise Ratio (SNR) and Spurious-Free Dynamic Range (SFDR) comparisons between the two power supplies, which demonstrate the same performance.
Wide-Bandwidth and High-Voltage Arbitrary Waveform Generator Front End
TIDA-00075: This design shows how to use an active interface with the current sink output of the DAC5682Z - typical applications for this include front ends for arbitrary waveform generators. The EVM includes the DAC5682Z for digital-to-analog conversion, an OPA695 to demonstrate an active interface implementation using a wide bandwidth operational amplifier and a THS3091 and THS3095 to showcase an operational amplifier with large voltage swing. Also included on board are a CDCM7005, VCXO and Reference for clock generation, and linear regulators for voltage regulation. Communication to the EVM is accomplished via a USB interface and GUI software.
