NB3N5573
Clock Generator, Crystal to
25 MHz, 100 MHz, 125 MHz,
200 MHz, 3.3 V, with Dual
HCSL
Description
The NB
3N5573 is a precision, low phase noise clock generator that
supports PCI Express and Ethernet requirements. The device accepts a
25 MHz fundamental mode parallel resonant crystal and generates a
differential HCSL output at 25 MHz, 100 MHz, 125 MHz or 200 MHz
clock frequencies. Outputs can interface with LVDS with proper
termination (See Figure 4).
This device is housed in 5.0 mm x 4.4 mm narrow body TSSOP 16
pin package.
Features
• Uses 25 MHz Fundamental Mode Parallel Resonant Crystal
• External Loop Filter is Not Required
• HCSL Differential Output or LVDS with Proper Termination
• Four Selectable Multipliers of the Input Frequency
• Output Enable with Tri−State Outputs
• PCIe Gen1, Gen2, Gen3, Gen4, QPI, UPI Jitter Compliant
• Phase Noise: @ 100 MHz
Offset Noise Power
100 Hz −109.4 dBc
1 kHz −127.8 dBc
10 kHz −136.2 dBc
100 kHz −138.8 dBc
1 MHz −138.2 dBc
10 MHz −161.4 dBc
20 MHz −163.00 dBc
• Typical Period Jitter RMS of 1.5 ps
• Operating Range 3.3 V ±10%
• Industrial Temperature Range −40°C to +85°C
• These are Pb−Free Devices
