HI3-400/12
The HI3-400/12 card provides 12 inputs for SDI formats, supporting signals from 3Mbps all the way up to 3G including SD-SDI, HD-SDI, 3G-SDI, dual- or quad-link 4K, and DVB/ASI. Reclocking is provided as standard for the best possible signal quality on all SMPTE-standard formats.

the HI3-400/12 Multi-rate SDI Input Card is designed to receive 12 individual single ended data streams at data rates between 3 Megabits per second to 3 Gigabits per second. This range allows the card to receive SMPTE SDI signals in the 259, 292 and 424 standards, as well as non SMPTE standards like DVB-ASI, AES-3 audio, and SMPTE-310 signals.
Circuit Description
The first stage of the card equalizes the signal to remove deterministic cable rolloff. It is capable of the following cable lengths for some standard SDI data rates:
• SMPTE-259C – 270 Mb/Sec – 350 Meter equalization capability
• SMPTE-292 – 1.485 Gb/Sec – 150 Meter equalization capability
• SMPTE-424 – 2.970 Gb/Sec100 Meter equalization capability
The equalization stage also provides an indication that the equalizer has detected and is equalizing a signal.
After the cable equalization stage, the signal enters a 1 x 4 fanout distribution stage. One of these four signals is driven to each individual crosspoint in the system. In this fashion, every crosspoint card has an identical copy of each input signal in the system.
Controls and Indicators
Controls:
P1 Standard UT400 diagnostic port provides detailed operational status and control for this card.
Indicators:
Communications indicator – Yellow. Illuminated when the card has been addressed by the Frame Controller Module.
PS Fail LED. Red – Illuminated when the 3.3V power supply falls out of +5% tolerance.
Signal Present Detection LEDs (12). Green – One of these LEDs is present on the front edge of the card for each input signal. They are labeled as ‘Carrier Detect’ 1-12. To use the Carrier detect numbering to help identify whether or not an input is present in the router, the CD1-12 must be translated to the particular router slot the card is inserted in.
