DATASHEET ISL59960 FN8358 Rev 0.00 960MegaQ: An Automatic 960H and Composite Video Equalizer, Fully-Adaptive December 18, 2012 to 4000 Feet The ISL59960 is a single-channel adaptive equalizer for 960H Features (WD1) or 720H (D1) composite video designed to Equalizes both 960H and 720H video automatically compensate for long runs of CAT 5/CAT 6 or RG-59 cable, producing high quality video output with no user Equalizes up to 4000 feet of Cat 5/Cat 6 and up to 5000 interaction. The ISL59960 equalizes up to 4000 feet (1200 feet (1500m) of RG-59 meters) of CAT 5/CAT 6 cable. Fully automatic, stand-alone operation - no user adjustment 960MegaQ compensates for high frequency cable losses of required up to 70dB at 9MHz, as well as source amplitude variations up 13MHz -3dB bandwidth to 3dB. 8kV ESD protection on all inputs The ISL59960 operates from a single +5V supply. Inputs are Automatic cable type compensation AC-coupled and internally DC-restored. The output can drive Compatible with color or monochrome, 960H, NTSC or PAL 2V into two source-terminated 75 loads (AC-coupled or P-P signals DC-coupled). Automatic polarity detection and inversion Related Literature Compensates for 3dB source variation (in addition to cable AN1780 ISL59605-Catx-EVZ/ISL59960-Catx-EVZ losses) Evaluation Board (Stand-Alone Evaluation Board) Optional serial interface adds additional functionality AN1776 ISL59603-Coax-EVZ/ISL59960-Coax-EVZ Works with single-ended or differential inputs Evaluation Board (Stand-Alone Evaluation Board) Output drives up to two 150 video loads AN1775 ISL59605-SPI-EVALZ/ISL59960-SPI-EVALZ Evaluation Board (with Serial Interface) Operation (Rev 5.0) Applications (Evaluation Board with USB Serial Interface) Surveillance video Video distribution Typical Application APPLICATION CIRCUIT FOR CAT X CABLE 960H, NTSC, PAL, MONOCHROME CAMERA/ 1.0F VIDEO SOURCE 75 IN+ OUT 50 1k 300 ISL59960 0.047F GND CFB 50 1.0F 1500pF PASSIVE IN- UP TO 4000 FEET OF BALUN TV/DVR CAT 5/CAT 6 CABLE V CC APPLICATION CIRCUIT FOR COAXIAL CABLE 0.1F 960H, NTSC, PAL, MONOCHROME CAMERA/ 10k VIDEO SOURCE 1.0F 75.0 IN+ OUT 37.5 1k ISL59960 300 0.047F GND 0 TO 5000 FEET OVER RG-59 CFB 37.5 COPPER-CORE COAXIAL CABLE 1.0F 1500pF IN- TV/DVR 0.1F FN8358 Rev 0.00 Page 1 of 17 December 18, 2012ISL59960 Pin Configuration ISL59960 (20 LD QFN) TOP VIEW 20 19 18 17 16 GND V 1 15 REF V 2 14 GND DD1 THERMAL PAD IN+ VIDEO OUT 3 13 (SOLDER TO GND) GND 4 12 CFB IN- V 5 11 DD2 67 8 9 10 Block Diagram CLAMP AND IN+ DIFFERENTIAL TO VIDEO OUT EQUALIZER AMP LPF SINGLE-ENDED IN- CONVERTER CFB V REF DIGITAL INTERFACE GEN FN8358 Rev 0.00 Page 2 of 17 December 18, 2012 VREF EQ DISABLE COLOR INVERT GND SD LOCKED EQ DISABLE SCK COLOR SEN FREEZE INVERT GND LOCKED FREEZE SEN SCK SD
