概要
説明
The 843251I-12 is a 10Gb Ethernet clock generator that uses an 18pF parallel resonant crystal over the range of 23.2MHz - 30MHz. For Ethernet applications, a 25MHz crystal is used. The 843251I- 12 uses our 3rd generation low phase noise VCO technology, and can achieve <1ps rms phase jitter performance over the 1.875MHz - 20MHz integration range. The 843251I-12 is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.
