 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.
