Product Features
- Easy evaluation of TLC5540 (40MSPS) and TLC5510 (20MSPS)
- High-speed low-noise layout guidelines
- Flexible support circuits for various evaluation modes
- Access to all digital control pins
- Large user prototyping areas
The TLC5540 is a high-speed, analog-to-digital converter (ADC)
that digitizes wide bandwidth analog signals with 8-bit resolution
at a minimum conversion rate of 40MSPS. Applications for the TLC5540
include digital television, CCD interfacing, digital down converters,
video conferencing, and digital set-top box. An evaluation module
is available to assist system designers in evaluating the performance
and features of the TLC5540.
The TLC5540EVM is a complete stand-alone PCB designed to allow
quick and accurate evaluation of the TLC5540. On-board circuitry
includes the device being tested (TLC5540), wide bandwidth input
buffer amplifier, control logic, and latches. A flexible interface
is provided with selectable jumper options, convenient connectors,
and large analog and digital prototyping areas.
When designing a circuit that includes high-speed digital and
precision analog signals such as a high-speed ADC, proper grounding
and layout techniques are essential in achieving optimal performance.
The TLC5540EVM can be used as an example of appropriate layout
schemes and as a performance benchmark when designing your own
system.
The EVM comes with complete documentation that includes circuit
schematic, PCB layout, user manual, and a detailed data sheet.
The same EVM with TLC5510, 8-bit 20MSPS ADC can be purchased for
quick evaluation of the TLC5510.
