ASM2I2318ANZ - 3.3V SDRAM Buffer

General Description

The ASM2I2318ANZ is a 3.3V buffer designed to distribute high-speed clocks in PC applications.

The part has 18 outputs, 16 of which can be used to drive up to four SDRAM DIMMs, and the remaining can be used for external feedback to a PLL.

Key Features

  • One input to 18 output Buffer/Driver.
  • Supports up to four SDRAM DIMMs.
  • Two additional outputs for feedback.
  • Serial interface for individual output control.
  • Low skew outputs (< 250 pS).
  • Up to 133 MHz operation.
  • Dedicated OE pin for testing.
  • Space-saving 48 Pin SSOP package.
  • 3.3V operation Functional.

June 2005 rev 0.3 ASM2I2318ANZ 18 Output, 3.3V SDRAM Buffer for Desktop PCs with 3 DIMMs Features ƒ One input to 18 output Buffer/Driver ƒ Supports up to four SDRAM DIMMs ƒ Two additional outputs for feedback ƒ Serial interface for individual output control ƒ Low skew outputs (< 250 pS) ƒ Up to 133 MHz operation ƒ Dedicated OE pin for testing ƒ Space-saving 48 Pin SSOP package ƒ 3.3V operation Functional Description The ASM2I2318ANZ is a 3.3V buffer designed to distribute high-speed clocks in PC applications. The part has 18 outputs, 16 of which can be used to drive up to four SDRAM DIMMs, and the remaining can be used for external feedback to a PLL. The device operates at 3.3V and outputs can run up to 133MHz, thus making it compatible with Pentium II®* processors.
