840272I - Block Diagram
Description
The 840272I is a PLL-based Frequency Translator intended for use in Synchronous Ethernet applications. This high performance device is optimized to generate 25MHz and 8kHz LVCMOS clock outputs. The 840272I accepts the following differential or single-ended input signals: 161.1328125MHz (10GbE Mode), 156.25MHz (1GbE Mode), or 125MHz (Recovered clock from 10/100/1000BaseT Ethernet PHY). The extended temperature range supports telecommunication and networking end equipment requirements.
