Pocket HiFi C4 Pro: portable media player for audiophiles

by Laura Domela

“Under the hood, the Pocket HiFi C4 Pro uses CIRRUS Logic CS4398 Digital-Analog-Converter (DAC) and CS8422 SRC chip for a dynamic range of up to 120 dB, and a signal-to-noise (SNR) ratio of 108dB. it is capable of playing 24 bit/192 kHz WAV files, effectively bringing hi-fidelity to the portable world. the built-in headphone jack accepts both 3.5mm or 6.3mm plugs and features a built-in amp for 13.3mW of that extra oomph. you will also get SPDIF port for connecting this little portable hi-end device to stereo equipment.” via MikeShouts

Want early design analysis without simulation?

Sponsored by Siemens Digital Industries Software

Traditional verification methods are failing today's complex IC designs, which require a proactive, early-stage analysis approach. A shift-left methodology addresses IP block integration challenges and the limitations of traditional simulation and ERC tools. Insight Analyzer detects hard-to-find leakage issues across power domains, enabling early analysis without full simulation. Identify inefficiencies earlier to reduce rework, improve reliability, and enhance power performance.
