General Description

The ICS844003I is a 3 differential output LVDS Synthesizer designed to generate Ethernet referHiPerClockS™ ence clock frequencies and is a member of the HiPerClocks™ family of high performance clock solutions from ICS.

Using a 31.25MHz or 26.041666MHz, 18pF parallel resonant crystal, the following frequencies can be generated based on the settings of 4 frequency select pins (DIV_SEL[A1:A0], DIV_SEL[B1:B0]): 625MHz, 312.5MHz, 156.25MHz, and 125MHz.

The 844003I has 2 output banks, Bank A with 1 differential LVDS output pair and Bank B with 2 differential LVDS output pairs.

Key Features

  • Three LVDS outputs on two banks, A Bank with one LVDS pair and B Bank with 2 LVDS output pairs.
  • Using a 31.25MHz or 26.041666MHz crystal, the two output banks can be independently set for 625MHz, 312.5MHz, 156.25MHz or 125MHz.
  • Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended input.
  • VCO range: 560MHz to 700MHz.
  • RMS phase jitter @ 156.25MHz (1.875MHz - 20MHz): 0.63ps (typical).
  • 3.3V output supply mode.
  • -40°C to 85°.
