Important Regulatory and Safety Notices Before using this product and any associated equipment, refer to the “Important Safety Instructions” listed below so as to avoid personnel injury and to prevent product damage. Products may require specific equipment, and /or installation procedures be carried out to satisfy certain regulatory compliance requirements. Notices have been included in this publication to call attention to these specific requirements.
Environmental Information The equipment that you purchased required the extraction and use of natural resources for its production. It may contain hazardous substances that could impact health and the environment. To avoid the potential release of those substances into the environment and to diminish the need for the extraction of natural resources, Sierra Video Systems encourages you to use the appropriate take-back systems.

Introduction In This Chapter This chapter includes the following sections: • A Word of Thanks • Overview • Functional Block Diagram • Supported Audio and Video Formats • Documentation Terms A Word of Thanks Congratulations on choosing the openGearTM ADC-142 Analog to Digital Converter with Audio Embedding and Frame Sync. The ADC-142 is part of a full line of modular conversion gear for broadcast TV environments.
Audio rates are always 48kHz nominally but discrete AES inputs pass through sample rate converters to align them with the output timing. The sample rate converters can be disabled if necessary. Output AES is always precisely locked in time with the output video. Analog audio is differential input and sampled at 48 kHz with 0 dbFS digital equivalent to a +24 dBu analog. There are several advanced features available for the AES inputs.
Functional Block Diagram The ADC-142 has a very flexible signal flow path and feature set that combines several products into one compact package. This section diagrams the basic signal flow of your ADC-142 product. Video Analog Video Input Analog Video A/D 8 channels Diff.
Discrete AES Audio Output The ADC-142 can emit 16 channels (8 pairs) of discrete AES audio on 75 ohm BNC connections. The AES clock rate will be precisely locked to the output video rate. AES Audio Input Advanced Features AES Sample Rate Converter Bypass The card’s AES inputs have built in sample rate converters that are enabled by default. This allows the card to interface with asynchronous AES sources (sources who’s AES timing does not match the video reference timing.).
Installation and Setup In This Chapter This chapter includes the following sections: • Static Discharge • Unpacking • Rear Module Installation (Optional) • Board Installation • BNC Connections • Menu Structure • Factory Defaults Static Discharge Whenever handling the card and other related equipment, please observe all static discharge precautions as described in the following note: Static discharge can cause serious damage to sensitive semiconductor devices.
Rear Module Installation (Optional) If you are installing the card in a 8310-C-BNC or 8310-BNC frame (one with a 100 BNC rear module installed across the entire back plane), skip this section. If you are installing the card into a slot with no rear module, you should have ordered and received one of the following modules; ADC-142-A, ADC-142-B, ADC-142-C, or ADC-142-D. You will need to install it in your 8310 frame before you can connect cables.
Rear Modules Available for ADC-142 Figure 3. BNC Designations for the Card Rear Modules available for the ADC-142.
Board Installation Use the following steps to install the card in the openGearTM 8310 frame: 1. Warning Refer to the Owner’s Manual of the openGearTM 8310 frame to ensure that the frame is properly installed according to instructions. Heat and power distribution requirements within a frame may dictate specific slot placement of cards. Cards with many heat-producing components should be arranged to avoid areas of excess heat build-up, particularly in frames using convection cooling. 2.
Card Control and Status Card Status The card indicates the status of the input signal with the four blue LEDs labeled with the different supported formats (1080, 720, 625, 525). When the card has locked to a particular input format, that LED will be illuminated. When the card has not locked to a particular video format, the card will search all possible formats, and the lights will cycle rapidly. Menu Navigation The card can be configured from a menu system built in to the front card edge.
Proc Phase This is Chroma (C channel) phase adjustment, expressed in degrees, ranging from –360 to +360 in steps of one degree. Decoder SD Input Selects the input format for SD analog video. This must be changed to reflect the analog video format on the input for the ADC-142 to lock correctly. Valid SD formats are GBR, Component SMPTE, Component MII, Component Betacam, Component Y/C, and Composite. Decoder HD Input Selects the input format for HD analog video.
Audio Delay Specifies the amount of additional audio delay after matching video delay. When the change is under one and a half frames, the change in audio delay will be applied without interrupting audio. When changing audio delay more than a frame and a half at a time, there will be a slight audio glitch. Video Delay Reports the current amount of video delay in ms. Reset Frame Sync Resets the frame sync, clearing any buffered audio and video.
Output Gain The gain of each output is adjustable from +30 dB to –100 dB in 0.1 dB steps. After –100 dB gain is set to –Inf, which means that output is present, but muted. Output Polarity If set to “Norm” output polarity is the same as input polarity, if set to “Inv” the output polarity is inverted. This can be used to correct polarity errors in the input signals fed to the card. Tone Frequency This sets the frequency of the test tone for each of the four tone generators.
Restore Factory Settings In this parameter, move the toggle switch up to make the factory default settings active, and make the stored settings equal to the factory settings.
