ICS841664I - Integrated Device Technology

ICS841664I FEMTOCLOCK CRYSTAL-TO-HCSL CLOCK GENERATOR

The ICS841664I is an optimized sRIO clock IC S generator and member of the HiPerClocks™ family HiPerClockS™ of high-performance clock solutions from IDT. The device uses a 25MHz parallel crystal to generate 125MHz and 156.25MHz clock signals, replacing solutions requiring multiple oscillator and fanout buffer solutions. The device has excellent phase jitter .

Features

• Four differential HCSL clock outputs: configurable for sRIO (125MHz or 156.25MHz) clock signals One REF_OUT LVCMOS/LVTTL clock output
• Selectable crystal oscillator interface, 25MHz, 18pF parallel resonant crystal or LVCMOS/LVTTL single-ended reference clock input
• Supports the following output frequencies: 125MHz or 156.25MHz
• VCO: 625MHz
• PLL bypass and output enable
• RMS phase jitter, using a 25MHz crystal (1.875MHz - 20MHz): 0.35ps (typical) @ 125MHz
• Full 3.3V power supply mode
• -40°C to 85°C ambient operating temperature
• Available in both standard (RoHS 5) and lead-free (RoHS .
