SNAA378 January 2023 LMX1204
The LMX1204 device is a high-frequency clock distribution device. The device is designed for distributing a clock or local oscillator source to multiple transceiver channels. Each device supports four outputs. The devices can be cascaded when more channels are needed with negligible performance impact. The Cascaded LMX1204 Reference Design uses two layers of the LMX1204 device to facilitate 16 outputs. This report measures and analyzes the phase response between the outputs to illustrate typical phase error response with a realistic device and layout configuration.
