The National Instruments 778715-01 PXI Timing and Control Module, also referred to as the PXI-6653, is a high-performance device designed to provide precise timing and synchronization capabilities in industrial automation and control systems. With a CLKIN frequency range of 1 MHz to 105 MHz available in both sine and square wave formats, this module allows users to configure six general-purpose PFI connections as either inputs or outputs independently. The module supports PXI_Star and PXI_Trig signals for synchronizing PXI_STAR and RTSI/PXI triggers, enhancing system integration for complex applications.

Equipped with an onboard high-stability OCXO and a star trigger controller, the 778715-01 ensures low-skew triggering and extensive routing capabilities for clock and trigger signals among PXI start triggers and front panel connectors. The front panel features SMB male connectors for CLKOUT, CLKIN, and PFI signals, along with Access and Active LEDs for operational status indication. The module consumes a maximum of 2 A at +5 V, 600 mA at +3.3 V, 500 mA at +12 V, and operates at 0 A at -12 V, making it a versatile addition to any PXI system. It can synchronize the OCXO timebase with an external reference clock and generate a 10 MHz signal sourced from either PXI_CLK10 or its onboard OCXO. Additionally, when using a DDS source, it supports output frequencies from 1 Hz to 105 MHz, with AC-coupled outputs ensuring compatibility across diverse signal processing applications, making the 778715-01 ideal for both experimental and industrial synchronization needs.
