HCSL Reference Clocks

PublishTime：2022-04-27

High Speed Current Steering Logic [HCSL] outputs are found in Peripheral Component Interconnect Express [PCIe] applications, Intel and Nvidia chipsets among others. HCSL is a differential output standard, similar to LVPECL, providing a high impedance output with fast switching times. Other advantages include aver-age power consumption when compared to LVDS and LVPECL and low phase jitter performance.
The differential output has a 15mA current source de-rived from an open emitter or source, with untermina-ted drains, that require external 50 ohm resistors ter-minated to ground. If needed, a 10 to 30 ohm series resistor can be added to reduce overshoot or ringing in waveform.
