AXN/HSS/401

The AXN/HSS/401 is a high speed synchronous serial module with four input channels. It interfaces to scientific instruments at up to 50 Mbps. Each channels is made up of four signals: Load Enable, Gate Clock Out, Gated Clock In (echo), and Serial Data In. All signals are Low Voltage Differential Signals (LVDS). 

Additionally there are eight programmable LVDS outputs, which can be assigned one of four, functions: Major Frame, Minor Frame, Word Pulse, and Bit Clock. 

An internal PLL maintains synchronization between the AXN/HSS/401 internal acquisition cycle and the acquisition cycles of the Axon chassis so that sampled data can be redistributed via PCM using an Axon encoder module (such as an AXN/ENC/402) in a synchronous manner.
