Description
The PI6LC48P0101 is a 10Gb Ethernet Clock Generator. The
PI6LC48P0101 uses an 18pF parallel resonant crystal over the
range of 23.2MHz - 30MHz. For Ethernet applications, a 25MHz
crystal is used. The PI6LC48P0101 can achieve <0.5ps RMS
phase jitter performance over the 12kHz - 20MHz integration
range. The PI6LC48P0101 is packaged in a small 8-pin TSSOP,
making it ideal for use in systems with limited board space.
