Abstract

LMX1205 is a versatile clocking product which can act as multiplier, divider, and buffer. When LMX1205 is used in the signal chain and deterministic nature across the signal chain is needed, certain sequence of events have to be performed. This deterministic nature of clock bringup in signal chain helps in predictable JESD link and post processing following it. This app note covers the sequence of events to be followed to maintain the deterministic nature.
