RENESAS 8A34004E-000NBG Frequency Synthesiser IC, 4 Outputs, 1.71 V to 3.465 V, VFQFPN-EP-48, -40 °C to 85 °C

8A34004E-000NBG is a synchronization management unit (PMU). It provides tools to manage timing references, clock sources, and timing paths for IEEE 1588 and synchronous Ethernet (SyncE) based clocks. The PLL channels can act independently as frequency synthesizers, jitter attenuators, digitally controlled oscillators (DCO), or digital phase lock loops (DPLL). The filter/servo software is designed to suppress the affects of Packet Delay Variation (PDV) on packet based timing signals � it can be used with protocol stacks for IEEE 1588 or other packet-based timing protocols. Typical application includes core and access IP switches / routers, synchronous Ethernet equipment, telecom boundary clocks (T-BCs) and T-TSCs according to ITU-T G.8273.2, 10Gb, 40Gb, and 100Gb Ethernet interfaces, central office timing source and distribution, wireless infrastructure for 4.5G and 5G network equipment.
