Renesas Electronics 9DMU/V PCIe Gen1-2-3 Clock Multiplexers

Renesas Electronics 9DMU/V PCIe Gen1-2-3 Clock Multiplexers are offered as part of its SoC, Very Low Power (VLP), and Ultra-Low Power PCIe Gen1-2-3 family. The 1.5V 9DMU series and pin-compatible 1.8V 9DMV clock multiplexers are designed as two-input devices with either one of four outputs. These clock multiplexers are available with external terminations or integrated 100Ω terminations. In addition, the designer can choose between asynchronous switching or synchronous switching modes. The Renesas Electronics 9DMU and 9DMV series support PCIe Gen1, Gen2, and Gen3 (Gen 1-2-3) phase jitter requirements. 

These devices deliver enterprise-level performance for space and power-constrained designs. Using the 9DMU/V PCIe Gen1-2-3 Clock Multiplexers, designers can reduce power consumption and board space compared to standard 3.3V HCSL devices.

The 9DMU/V PCIe Gen1-2-3 Clock Multiplexers are ideal for DSLR cameras, multi-function printers, solid-state drives, vehicle infotainment systems, servers, micro-servers, set-top boxes, PCIe-based storage arrays, and a variety of other PCIe-based applications.

Features

  • LP-HCSL outputs w/integrated terminations; saves 2-16 resistors compared to standard HCSL outputs
  • HCSL differential inputs; can be driven by common clock sources
  • Selectable asynchronous or glitch-free switching; allows the mux to be selected at power-up even if both inputs are not running, then transition to glitch-free switching mode
  • OE# pins support DIF power management
  • DIF phase jitter is PCIe Gen1-2-3 compliant
  • Spread spectrum compatible and supports EMI reduction
  • Space-saving VFQFPN package uses minimal board space
