843252-04数据手册Renesas中文资料规格书

描述 Description

The 843252-04 is a 10Gb/12Gb Ethernet Clock Generator. The 843252-04 can synthesize 10 Gigabit Ethernet and 12 Gigabit Ethernet with a 25MHz crystal. It can also generate SATA and 10Gb Fibre Channel reference clock frequencies with the appropriate choice of crystals. The 843252-04 has excellent phase jitter performance and is packaged in a small 16-pin TSSOP, making it ideal for use in systems with limited board space.
