9SQ440中文资料CK440Q PCIe Gen6 Server Clock Generator数据手册Renesas规格书

描述 Description

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.

特性 Features

• 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
