Was ist das für ein Bauteil (3 Pins) ? (Elektronik)

The high-speed data rate (THSDRAT) is nominally 480.00 Mb/s, with a required bit rate accuracy of ±500 ppm.
For hosts, hubs, and high-speed capable functions, the required data-rate accuracy when transmitting at any
speed is ±0.05% (500 ppm). The full-speed rate for such hubs and functions is TFDRATHS. The low-speed rate for
such hubs is TLDRATHS (a low-speed function must not support high-speed).
The full-speed data rate is nominally 12.000 Mb/s. For full-speed only functions, the required data-rate when
transmitting (TFDRATE) is 12.000 Mb/s ±0.25% (2,500 ppm).
The low-speed data rate is nominally 1.50 Mb/s. For low-speed functions, the required data-rate when
transmitting (TLDRATE) is 1.50 Mb/s ±1.5% (15,000 ppm). This allows the use of resonators in low cost, lowspeed
devices.
