Description

The PI6LC58S1101 is very low jitter clock generator target for

applications that demand extremely low phase noise, such as

10GbE, 40GbE, 100GbE, and 400GbE. It uses Diodes' proprietary

LC VCO-based PLL design to achieve an optimum combination

of those popular networking clock frequencies and low phase

noise performance along with high power supply noise rejection.

The PI6LC58S1101 has four output banks which can be config-

ured independently for different frequencies and different output

signaling types based on control pins. The pin control method

provides an easy way to configure the device at the hardware

level.
