SSTE32882KA1 - 1.25V/1.35V/1.5V REGISTERING CLOCK DRIVER

Description

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.

Features

  • Pinout optimizes DDR3 RDIMM PCB layout.
  • DDR3-800/1066/1333/1600/1866/2133 rate.
  • 1-to-2 Register Outputs and 1-to-4 Clock Pair Outputs support stacked DDR3 RDIMMs.
  • Phase Lock Loop clock driver for buffering one differential clock pair (CK and CK) and distributing to four differential outputs.
  • Supports LVCMOS switching levels on the RESET and MIRROR inputs.
  • Checks priority on DIMM-independent data inputs.
  • Supports dynamic 1T/3T timing.

DATASHEET 1.25V/1.35V/1.5V REGISTERING CLOCK DRIVER WITH PARITY TEST AND QUAD CHIP SELECT SSTE32882KA1 Description 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 25Ω to 50Ω 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.
