843022I-48中文资料FemtoClock® Crystal-to-3.3V,2.5V LVPECL Clock Generator数据手册Renesas规格书

描述 Description

The 843022I-48 is a Fibre Channel Clock Generator and a member of the high performance devices from IDT. The 843022I-48 uses a 25MHz crystal to synthesize 125MHz or 75MHz. The 843022I-48 has excellent phase jitter performance, over the 12kHz – 20MHz integration range. The 843022I-48 is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.
