Renesas Electronics 871S1022EKLF, PLL Clock Generator 32-Pin VFQFPN-32

The Renesas Electronics ICS871S1022 is a PLL-based clock generator specifically designed for PCI Express Clock Generation applications. The device generates 100MHz, 125MHz, 250MHz or 500MHz from either a 25MHz fundamental mode crystal or a 100MHz recovered clock.

Four 0.7V differential output pairs
One differential clock input pair
CLK, nCLK pair can accept the following differential
input levels: LVPECL, LVDS, LVHSTL, HCSL
Crystal oscillator interface designed for 25MHz, 18pF parallel
resonant crystal
RMS phase jitter at 100MHz, using a 25MHz crystal
(12kHz – 20MHz): 0.608ps (typical)
High frequency jitter attenuator mode has high PLL bandwidth
which allows for better input tracking
Supports PCI Express Spread-Spectrum Clocking
PCI Express Gen 1, 2 and 3 jitter compliant
