SP Devices provides signal processing IP for digital performance enhancement of analog-to-digital conversion and input signal paths. The IP products are available for implementation in application specific integrated circuits (ASICs) or for integration on field-programmable gate array (FPGA) platforms. Our portfolio of products enables our customers to build systems with state-of-the-art analog-to-digital performance that enables advances in areas such as broadband communcation transceivers, instrumentation, high-speed data acquisition, Radar, and signals intelligence. We also incorporate our IP in our range of high-speed digitizers.
Time‑interleaving of analog‑to‑digital converters (ADCs) is a way to increase the overall system sample rate by using several ADCs in parallel. The challenge is to handle the mismatch between the individual ADCs, especially at higher frequencies.
Digital post‑linearization increases the effective resolution of analog‑to‑digital conversions. The ADL linearization technology developed by SP Devices suppresses performance-limiting non‑linearities of ADCs and the preceding signal path (amplifiers, filters, buffers, etc.).
Digital I/Q imbalance correction match the in-phase and quadrature signal paths in radio architectures employing complex demodulators such as direct down-conversion receivers. The distortion due to signal path imbalances is attenuated effectively over a large bandwidth.
