LMK00725 Low Skew, 1-to-5, Differential-to-3.3V LVPECL Fanout Buffer

DESCRIPTION
The LMK00725 is a low skew, high-performance clock fanout buffer which can distribute up to five 3.3V LVPECL outputs from one of two inputs, which can accept differential or single-ended inputs. The clock enable input is synchronized internally to eliminate runt or glitch pulses on the outputs when the clock enable pin is asserted or de-asserted. The low additive jitter and phase noise floor and ensured output and part-to-part skew characteristics make the LMK00725 ideal for applications demanding high performance and repeatability.

FEATURES
• Five 3.3V Differential LVPECL Outputs
   – Additive Jitter: 43 fs RMS (typ) @ 312.5 MHz
   – Noise Floor (≥1 MHz offset): -158 dBc/Hz
      (typ) @ 312.5 MHz
   – Output Frequency: 650 MHz (max)
   – Output Skew: 35 ps (max)
   – Part-to-Part Skew: 100 ps (max)
   – Propagation Delay: 0.37 ns (max)
• Two Differential Input Pairs (pin-selectable)
   – CLKx, nCLK Input Pairs can accept
      LVPECL, LVDS, HCSL, SSTL, LVHSTL, or
      Single-Ended Signals
• Synchronous Clock Enable
• Power Supply: 3.3V ± 5%
• Package: 20-Lead TSSOP
• Industrial Temperature Range: -40ºC to +85ºC

APPLICATIONS
• Wireless and Wired Infrastructure
• Networking and Data Communications
• Servers and Computing
• Medical Imaging
• Portable Test and Measurement
• High-End A/V
