FEMTOCLOCKS CRYSTAL-TO-LVDS FREQUENCY SYNTHESIZER ICS844003 The ICS844003 is a 3 differential output LVDS Synthesizer designed to generate Ethernet reference HiPerClockS clock frequencies and is a member of the HiPerClocks family of high performance clock solutions from IDT. Using a 31.25MHz or 26.041666MHz, 18pF parallel resonant crystal, the following frequencies can be generated based on the settings of four frequency select pins DIV_SEL[A1:A0], DIV_SEL[B1:B0] : 625MHz, 312.5MHz, 156.25MHz, and 125MHz. The ICS844003 has two output banks, Bank A with one differential LVDS output pair and Bank B with two differential LVDS output pairs. • 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 The two banks have their own dedicated frequency select pins and can be independently set for the frequencies mentioned above. The ICS844003 uses IDT’s 3rd generation low phase noise VCO technology and can achieve 1ps or lower typical rms phase jitter, easily meeting Ethernet jitter requirements.

FEMTOCLOCKS CRYSTAL-TO-LVDS FREQUENCY SYNTHESIZER

ICS844003

The ICS844003 is a 3 differential output LVDS

Synthesizer designed to generate Ethernet reference

HiPerClockS
clock frequencies and is a member of the

HiPerClocks family of high performance clock
solutions from IDT. Using a 31.25MHz or
26.041666MHz, 18pF parallel resonant crystal, the following
frequencies can be generated based on the settings of four
frequency select pins DIV_SEL[A1:A0], DIV_SEL[B1:B0] :
625MHz, 312.5MHz, 156.25MHz, and 125MHz. The ICS844003
has two output banks, Bank A with one differential LVDS output
pair and Bank B with two differential LVDS output pairs.
• 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

The two banks have their own dedicated frequency select pins and can be independently set for the frequencies mentioned above. The ICS844003 uses IDT’s 3rd generation low phase noise VCO technology and can achieve 1ps or lower typical rms phase jitter, easily meeting Ethernet jitter requirements.
