Description
The THAT7200 Series ICs are the first standalone JetPLL audio clock generators. Using jitter elimination technology invented and patented by audio clocking guru Chris Travis, these Phase Locked Loop ICs are specifically designed to optimize audio quality. This is essential in networked audio and USB audio applications, where each audio device must recreate and synchronize its own local clock to outside clocks.
External received clock sources often contain large jitter that causes distortion and noise when used to clock audio converters. The THAT7200 family of PLLs generates extremely clean clocks, attenuating received jitter by over 60dB, delivering less than 25ps of baseband jitter and ensuring frame synchronization per AES11. This enables high-performance ADCs and DACs, and the entire audio chain, to reach their full sonic potential.
The THAT 72xx products are pin and code compatible with the Cirrus CS2xxx family of parts. the 7200 is compatible with the CS2000, the 7210 is compatible with the CS2100, and the 7220 is compatible with the CS2200. All of the 72xx products have a more versatile set of features in Native JetPLL Mode. They also deliver better performance than the Cirrus parts in both Compatible and Native JetPLL Mode.
