Analog Devices Inc. ADF4378 Microwave Wideband Synthesizers
Analog Devices Inc. ADF4378 Microwave Wideband Synthesizers simplify clock alignment and calibration in multiple data converter and MxFE clock applications. The Analog Devices Inc. ADF4378 features automatic reference to output synchronization, matched reference to output delays across different conditions, and precise adjustment capability for reference to output delay (<±0.1ps jitter). Additionally, its general-purpose pulse retimer ensures accurate multichip clock and pulse alignment for SYSREF, SYNC, and multichip synchronization (MCS) setups. When paired with an IC handling reference and SYSREF signals, it supports JESD204B and JESD204C Subclass 1 solutions.Features
