Page 4: Introduction
SM08 is a receiver module compatible with the aCVi® Advanced Composite Video Interface format. SM08 accepts analogue aCVi® encoded video from both twisted pair and low-cost coaxial cable which it converts to HD-SDI format video. SM08... -
Page 5: Acvi Overview
The following is a brief overview of the aCVi® revision 2 interface (abbreviated to aCVi® in this document). aCVi® is a proprietary format, developed by SingMai Electronics, to transmit high definition video over long distances of coaxial or twisted pair cable. aCVi® is an update to the previous version, specifically designed to interface directly to image sensors, although it may also be used to transmit conventional video sources. -

SDI or DVI video sources (e.g. a video camera) and simultaneously drives both coaxial and twisted-pair cable. The receiver module is the SM08. This module accepts either twisted-pair or coaxial cable and converts the aCVi® video to an HD-SDI output for a TV monitor or video recorder. -

2 ‘VIDEO-‘ (inverted) signal. If the aCVi® input is valid and can be locked to, the yellow ‘Lock’ LED will light – the SM08 automatically detects the input video standard. Once the aCVi® decoder has locked and is decoding the yellow ‘SDI lock LED’... -

4. Circuit description Figures 6-14 show the schematics for the SM08. Below is a brief technical description of the module. Sheet 1. J3 is the 5VDC power input connector to the SM08 module. The 5VDC is protected from over-voltage and reverse polarity inputs by D1, D2 and resettable fuse, F1. The input is then filtered by L1 and C2 to provide the ‘clean’... - Page 9 The scrambled signal is then multiplexed into 5 data streams at 148.5MHz which are driven as LVDS outputs, together with an LVDS clock, to the HD-SDI serialiser IC, U18, which converts these five data signals into one 1.485GHz, HD-SDI compatible, output (J9).
