 The 1145 is the first chip, and it doesn't offer full S-video output.  However, you can achieve a decent S-video signal from the chip by amping the two Y/C outputs from pins 15 and 16.  See the schematic [[http://i18.photobucket.com/albums/b134/Segasonicfan/Schematics/SVideoIC.png|here]] The 1145 was used in most early consoles, up to and including the Genesis and Neo Geo.  The MB3514 is pin-for-pin the same chip and was used for the Sega CDX and other Genesis models/variants. The 1645 powered many later consoles, including the Genesis 3, Saturn and NeoGeo CD/CDZ. One noted difference between the Sony chip and Fujitsu versions is that the Fujitsu circuit requires far less external components.  The Samsung KA2915 is another clone used in some Genesis model 2 systems and is known for being the worst encoder of the bunch.  The 2075 was never used in a console as far as I know, however it was considered for use in Sega's Saturn (it used too much power and had to be dropped). The 1145 is the first chip, and it doesn't offer full S-video output.  However, you can achieve a decent S-video signal from the chip by amping the two Y/C outputs from pins 15 and 16.  See the schematic [[http://i18.photobucket.com/albums/b134/Segasonicfan/Schematics/SVideoIC.png|here]] The 1145 was used in most early consoles, up to and including the Genesis and Neo Geo.  The MB3514 is pin-for-pin the same chip and was used for the Sega CDX and other Genesis models/variants.
