概要

説明

The 9SQ440 is an Intel CK440 main clock synthesizer for Intel cloud and HPC platforms, and newer Intel-based server platforms. 9SQ440 is a single-chip, PCIe Gen6 compliant, and is designed to work as a complete clock solution or in combination with DB2000Q-compliant clock buffers to provide point-to-point clocks to multiple receiving agents.

特長

  • PCIe Gen6 phase jitter < 40fs rms
  • 3 x 25MHz dedicated output pairs
  • 7 x 100MHz dedicated output pairs with individual OE# pins
  • 9 MXCLK output pairs multiplexable between 100MHz and 25MHz
  • 3.3V operation
  • 85Ω differential Low-Power HCSL (LP-HCSL) outputs eliminate 80 resistors, saving 130mm2 of area
  • 9 selectable SMBus addresses
  • Supports 0%, -0.3% and -0.5% spread-spectrum amounts
  • Side-Band Interface allows real-time hardware control of all output enables
  • OE# pin control of 100M[6:0] supports PCIe slot CLKREQ#
  • Dedicated Platform Time input and output clocks (PFT_IN and PFT_OUT)
  • 8 × 8 mm dual-row 100-VFQFPN
  • -40°C to +85°C operating temperature range
