Microchip / Datum BC11576-1000 A J1 to BNC Cable

The BC11576-1000 A is a J1 to BNC cable assembly that bridges J1 interface ports to standard BNC connectors. Engineered for precision timing and frequency applications, this cable accessory connects to Datum time and frequency processor modules including the bc635PCI, bc637PCI, bc635PCI-U, bc635PCI-V2, and bc637PCI-U platforms.

The cable facilitates signal transmission across multiple timing and frequency reference channels. Within compatible modules, it enables connections for time code input, time code output, 1PPS input, 1PPS output, event input, and periodic output depending on specific board configuration. Signal integrity is maintained throughout the signal path to support precision timing operations.
