Here are details for my 3 main units:
#1
20040601xxxx
Either Cypress (manufacturer) or AVToolbox (rebadger) defaced all the chips. You cannot read any of them. The chips appear to be sanded down, and some sort of gray powder substance was left (possibly the dust from sanding).
#2
20050205xxxx
IC1 = SAA7114H
IC2 = CY37064VP44 (FPGA?)
IC3 = KCL KT88V422SA-2533, 0411-BS
IC4 = KCL KT88V422SA-2533, 0411-BS
IC5 = SAA7129H
IC6 = LTB-100 V2.0 A0412
IC7 = 24LC02B/SN0425 (Microchip brand?) EEPROM - still in production 2018
IC8 = Sanken 424 347, 8033JD
#3
20060705xxxx
IC1 = SAA7114H
IC2 = CY37064VP44 (FPGA?)
IC3 = KCL KT88V422MA-2533, 0537-BS
IC4 = KCL KT88V422MA-2533, 0537-BS
IC5 = SAA7129H
IC6 = LTB-100 V2.0 S0605
IC7 = 24LC02B/SN0553 (Microchip brand?) EEPROM - still in production 2018
IC8 = Sanken 5D2 618, 8033JD
The SAA = Philips/NXP
CY3706VP44 = in-house chip by Cypress, and rebadged by some no-name Chinese companies
I can find almost zero information on KCL. I believe it may be a Chinese no-name rebadge of somebody else.
My "IC6" is not labeled as such on my 2005 unit. It skips from IC5 to IC7, and this chip falls between them.
The main difference appears to be:
- IC2, CPLD/EEPROM, Altera vs. Cypress (not same Cypress)
- IC3/4, KCL vs. AverLogic
- IC6, V2.0 vs V2.1 vs V2.2
I doubt that the SAA7129 or SAA7114 changes much, if at all, and are simply rebranded for the date it was made. NXP = Philips = Trident, in terms of the chips. Possible, but doubt it.
I doubt versions of IC6 does much. Perhaps, but probably not as likely.
The culprit is probably AverLogic or Altera/Intel. However, the issue looks to be the frame sync, specifically the frame buffer. So whatever chip controls the framesync is probably the dud.
