Renesas Electronics 9DML0451
The 9DML0441 and 9DML0451 devices are 3.3V members of Renesas' Full-Featured PCIe family. They support PCIe Gen1–6 Common Clocked (CC), Separate Reference no Spread (SRnS), and Independent Reference (IR) clock architectures. The parts provide a choice of asynchronous or glitch-free, gapped-clock switching modes, and offer a choice of integrated output terminations for direct connection to 85Ω or 100Ω transmission lines.DESCRIPTION
APPLICATIONS
● Servers● ATE
● Storage
● Master/Slave applications Output
FEATURES
● Four 1–200MHz Low-Power HCSL (LP-HCSL) DIF pairs● 9DML0441 default ZOUT = 100
● 9DML0451 default ZOUT = 85
● See AN-891 for easy termination to other logic levels
FEATURES
● Direct connection to 100 (xx41) or 85 (xx51) transmission lines saves up to 16 resistors● 79mW typical power consumption
● Spread Spectrum Clocking (SSC) compatible
● OE# pins for each output
● HCSL-compatible differential inputs
● Selectable asynchronous or glitch-free, gapped-clock switching; allows the mux to be selected at power up even if both inputs are not running, then transition to glitch-free switching mode
● Space saving 4 × 4 mm 24-VFQFPN
● Contact factory for customized versions Key Specifications
