Module Overview Fail-Safe Protection Switch The Avenue 7465 HD/SD Sync Changeover Switch module and Avenue 9465 3G/HD/SD Sync Changeover Switch module are fail-safe protection switches for monitoring and switching critical sync reference signals from any of Ensemble Designs’ reference generators or third-party sync pulse generators. -
Page 5: Monitoring
7465 Sync Changeover Switch and 9465 3G Sync Changeover Switch Monitoring Fault conditions can be monitored with an external alarm system or other device through the 15-pin Control connector on the rear of the Avenue 7465 or Avenue 9465. Signal status from this connector can be monitored by a device to show Primary and Secondary signal status and the current position of the protect switch (Primary or Secondary). -

Page 13: Module Configuration And Control
7465 Sync Changeover Switch and 9465 3G Sync Changeover Switch Because both the NO and NC connections are provided, it is possible to have independent status lines for each of the two states of a status signal. For example, if the jumper is set to +5V, the Primary NO output will source +5V when the relay is in the normal position (Signal Failed) and the Primary NC output will source the +5V when the relay is closed (Signal Good). -

7465 Sync Changeover Switch and 9465 3G Sync Changeover Switch Glossary AES/EBU The digital audio standard defined as a joint effort of the Audio Engineering Society and the European Broadcast Union. AES/EBU or AES3 describes a serial bitstream that carries two audio channels, thus an AES stream is a stereo pair. - Page 30 7465 Sync Changeover Switch and 9465 3G Sync Changeover Switch signal with more detail or fidelity. Thus, a video digitizer with 12 bits of resolution will capture 4 times as much detail as one with 10 bits. Blanking The Horizontal and Vertical blanking intervals of a television signal refer to the time periods between lines and between fields.

7465 Sync Changeover Switch and 9465 3G Sync Changeover Switch can also add complexity to signal handling issues because the audio content can no longer be treated independently of the video. Eye Pattern To analyze a digital bitstream, the signal can be displayed visually on an oscilloscope by triggering the horizontal timebase with a clock extracted from the stream. - Page 33 7465 Sync Changeover Switch and 9465 3G Sync Changeover Switch HDMI The High Definition Multimedia Interface comes to us from the consumer marketplace where it is becoming the de facto standard for the digital interconnect of display devices to audio and video sources.
- Page 34 7465 Sync Changeover Switch and 9465 3G Sync Changeover Switch allowable jitter is 740 picoseconds, or 0.2 UI (Unit Interval – one bit width). For 1.485 Gb/s HD, the same 0.2UI spec corresponds to just 135 pico seconds. LKFS LKFS (Loudness K-weighted relative to Full Scale) is a loudness amplitude level based on the ITU-R BS.1770 Loudness Measurement Method.
- Page 35 7465 Sync Changeover Switch and 9465 3G Sync Changeover Switch Optical An optical interface between two devices carries data by modulating a light source. This light source is typically a laser or laser diode (similar to an LED) which is turned on and off at the bitrate of the datastream.

7465 Sync Changeover Switch and 9465 3G Sync Changeover Switch ScH Phase Used in composite systems, ScH Phase measures the relative phase between the leading edge of sync on line 1 of field 1 and a continuous subcarrier sinewave. Due to the arithmetic details of both PAL and NTSC, this relationship is not the same at the beginning of each frame. - Page 37 7465 Sync Changeover Switch and 9465 3G Sync Changeover Switch mode fibers require particular care in their installation due to the extremely small optical aperture that they present at splice and connection points. See also Multi-mode. A Time Base Corrector is a system to reduce the Time Base Error in a signal to acceptable levels. It accomplishes this by using a FIFO (First In, First Out) memory.
