Renesas Electronics 9FGS9093
The 9FGS9093 is a simple, cost-effective, very highperformance clock generator supporting P9 and Open Power systems. It provides four low-jitter, 133 1/3MHz LP-HCSL outputs with or without spread spectrum.APPLICATIONS
● 1, 2, 3, and 4 socket P9 and Open Power systems Key Specifications● DIF cycle-to-cycle jitter < 50ps
● DIF output-to-output skew < 100ps
● OUT[3:0] phase jitter: 313ps rms (12kHz–20MHz) with SSC off
● OUT[3:0] phase jitter is PCIe Gen1–3 with SSC on/off
● REF phase jitter: 190fs rms Block Diagram XIN/CLKIN 33 1/3MHz XO vSEL_I2C# Control ^SEL0/SCL ^SEL1/SDA PLL ^OEA ^OEB
FEATURES
● 3.3V power supply; easy power supply hookup● OE[B:A] pins allow different power states
● 85Ω output impedance; eliminates up to 16 resistors and eases board routing
● Configuration selected via strapping pins or I2C; I2C interface not required for device control
● 350mW power consumption at 3.3V; reduces thermal concerns
● I2C address is 0b1101011x, where x is the write/read bit
● 4 × 4 mm 24-VFQFPN; minimal board space Output
