PL60708X
PCIe Octal, Ultra-Low Jitter,
HCSL Frequency Synthesizer General Description Features The PL607081 and PL607082 are members of the PCI
Express family of devices from Micrel and provide
extremely low-noise spread-spectrum clocks for PCI
Express requirements. п‚ Generates eight HCSL clock outputs
п‚ PL607081 output frequencies: 25MHz, 100MHz, or
200MHz
п‚ PL607082 output frequencies: 25MHz, 125MHz, or
250MHz
п‚ Spread spectrum for EMI reduction
п‚ 2.5V or 3.3V operating range
п‚ Typical phase jitter @ 100MHz: 320fs for 1.5MHz to
10MHz
п‚ Compliant with PCI Express Gen1, Gen2, and Gen3
п‚ Industrial temperature range (–40В°C to +85В°C)
п‚ RoHS and PFOS compliant
п‚ Available in a 44-pin 7mm Г— 7mm QFN package The devices operate from a 3.3V or 2.5V power supply
and synthesize eight HCSL output clocks. The PL607081
synthesizes 25MHz, 100MHz, or 200MHz frequencies and
the PL607082 synthesizes 25MHz, 125MHz, or 250MHz
frequencies. The PL60708x devices accept a 25MHz
crystal or LVCMOS reference clock. …
