LMK00334 Four-Output PCIe/Gen1/Gen2/Gen3/Gen4 Clock Buffer and Level Translator

Description
The LMK00334 device is a 4-output HCSL fanout buffer intended for high-frequency, low-jitter clock, data distribution, and level translation. The input clock can be selected from two universal inputs or one crystal input. The selected input clock is distributed to two banks of 2 HCSL outputs and one LVCMOS output. The LVCMOS output has a synchronous enable input for runt-pulse-free operation when enabled or disabled. The LMK00334 operates from a 3.3-V core supply and 3 independent 3.3-V or 2.5-V output supplies.
The LMK00334 provides high performance, versatility, and power efficiency, making it ideal for replacing fixed-output buffer devices while increasing timing margin in the system.

Features
• 3:1 Input Multiplexer
   – Two Universal Inputs Operate up to 400 MHz
      and Accept LVPECL, LVDS, CML, SSTL,
      HSTL, HCSL, or Single-Ended Clocks
   – One Crystal Input Accepts a 10- to 40-MHz
      Crystal or Single-Ended Clock
• Two Banks With 2 Differential Outputs Each
   – HCSL, or Hi-Z (Selectable)
   – Additive RMS Phase Jitter for PCIe
      Gen3/Gen4 at 100 MHz:
   – 30 fs RMS (typical)
• High PSRR: –72 dBc at 156.25 MHz
• LVCMOS Output With Synchronous Enable Input
• Pin-Controlled Configuration
• VCC Core Supply: 3.3 V ± 5%
• 3 Independent VCCO Output Supplies: 3.3 V/2.5 V ± 5%
• Industrial Temperature Range: –40°C to +85°C
• 32-Lead WQFN (5 mm × 5 mm)

Applications
• Clock Distribution and Level Translation for ADCs,
   DACs, Multi-Gigabit Ethernet, XAUI, Fibre
   Channel, SATA/SAS, SONET/SDH, CPRI, High
   Frequency Backplanes
• Switches, Routers, Line Cards, Timing Cards
• Servers, Computing, PCI Express (PCIe 3.0, 4.0)
• Remote Radio Units and Baseband Units
