RENESAS 8A34044E-000NLG Frequency Translator IC, 12 Outputs, 1.71 V to 3.465 V, VFQFPN-EP-72, -40 °C to 85 °C

8A34044E-000NLG is a four-channel universal frequency translator. It 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. Typical application includes core and access IP switches / routers, synchronous Ethernet equipment, 10Gb, 40Gb, and 100Gb Ethernet interfaces, wireless infrastructure for 4.5G and 5G network equipment and OTN muxponders and line cards.
