8A34044C-000NLG

8A34044C-000NLG four-channel universal frequency translator is a highly integrated timing device with four digital PLL (DPLL) and four digitally controlled oscillator (DCO) channels. The DPLLs can lock to external references or operate in free run and can be configured as DCOs. Each of the DCOs can be synchronized by any of the DPLLs or they can operate in free run. The DCOs can alternatively be controlled by an external algorithm for optical transport network (OTN) applications. Applications include core and access IP switches/routers, synchronous Ethernet equipment, 10Gb, 40Gb, and 100Gb Ethernet interfaces, wireless infrastructure for 4.5G and 5G network equipment, OTN muxponders and line cards.
