Hot-selling and scarce SSTE32882KB1AKG8 Pinout optimizes DDR3 RDIMM Clock Driver IC BGA spot stock

Product Descriptions

This 28-bit 1:2, or 26-bit 1:2 and 4-bit 1:1, registering clock  driver with parity is designed for 1.25V, 1.35V and 1.5V VDD operation.

All inputs are 1.25,1.35V and 1.5V CMOS compatible, except the  reset (RESET) and MIRROR inputs which are LVCMOS. All  outputs are 1.25V,1.35V and 1.5V CMOS edge-controlled drivers  optimized to drive single terminated 25 to 50 traces in DDR3  RDIMM applications, except the open-drain error (ERROUT)  output. The clock outputs (Yn and Yn) and control net outputs  QnCKEn, QnCSn and QnODTn are designed with a different  strength and skew to compensate for different loading and  equalize signal travel speed.​
