8P34S1204i

1:4 LVDS Output 1.8V Fanout Buffer

The IDT 8P34S1204i is a high-performance differential LVDS fanout buffer. The device is designed for the fanout of high-frequency, very low additive phase-noise clock and data signals. The 8P34S1204i is characterized to operate from a 1.8V power supply. Guaranteed low output-to-output and part-to-part skew characteristics make the 8P34S1204i ideal for those clock distribution applications demanding well-defined performance and repeatability. Two selectable differential inputs and four low skew outputs are available. The integrated bias voltage reference enables easy interfacing of AC-coupled signals to the device inputs. The device is optimized for low power consumption and low additive phase noise.

Features

  • Four low skew, low additive jitter LVDS output pairs
  • Two selectable, differential clock input pairs
  • Differential PCLK, nPCLK pairs can accept the following differential input levels: LVDS, LVPECL, CML
  • Maximum input clock frequency: 1.2GHz
  • LVCMOS/LVTTL interface levels for the control input (input select)
  • Output skew: 14ps (typical)
  • Propagation delay: 265ps (typical)
  • Low additive phase jitter, RMS
  • fREF = 156.25MHz, 10kHz - 20MHz: 42fs (typical)
  • Device current consumption (IDD): 70mA (typical) @1.89V
  • Full 1.8V supply voltage
  • Lead-free (RoHS 6), 16-Lead VFQFN package
  • -40°C to 85°C ambient operating temperature
