DATASHEET

GENERAL DESCRIPTION

FEATURES

The 841604 is an optimized PCIe and sRIO clock generator.

The device uses a 25MHz parallel crystal to generate 100MHz

and 125MHz clock signals, replacing solutions requiring multiple

oscillator and fanout buffer solutions.The device has excellent phase

jitter (< 1ps rms) suitable to clock components requiring precise and

low-jitter PCIe or sRIO or both clock signals. Designed for telecom,

networking and industrial applications, the 841604 can also drive the

high-speed sRIO and PCIe SerDes clock inputs of communication

processors, DSPs, switches and bridges.

• Four differential clock outputs: conﬁgurable for PCIe (100MHz)

and sRIO (125MHz) clock signals

• Selectable crystal oscillator interface, 25MHz, 18pF parallel

resonant crystal or LVCMOS/LVTTL single-ended reference

clock input

• Supports the following output frequencies:

100MHz or 125MHz

• VCO: 500MHz

• PLL bypass and output enable

• PCI Express (2.5Gb/s) and Gen 2 (5 Gb/s) jitter compliant

• RMS phase jitter, 125MHz, using a 25MHz crystal

(1.875MHz – 20MHz): 0.45ps (typical)

• Full 3.3V power supply mode

• -40°C to 85°C ambient operating temperature

• Available in lead-free (RoHS 6) package
