The Microchip/Datum bc336VME is a double-height 6U VMEbus module that decodes serial time code signals and provides advanced processing capabilities beyond standard single-board readers. The module accepts time code input via BNC connector and communicates with host systems through VMEbus A16:D08(O) data transfers. Register-based configuration enables users to select time code translation modes, activate time capture operations, define interrupt priorities and vectors, set heartbeat intervals, and apply propagation delay compensation. The bc336VME delivers microsecond-level time resolution and features a rate-programmable heartbeat pulse with onboard LED display for status indication.
