FEMTOCLOCKS™ CRYSTAL-TO-3.3V LVPECL FREQUENCY SYNTHESIZER
FEATURES
• Three 3.3V LVPECL outputs on two banks, A Bank with one LVPECL pair and B Bank with 2 LVPECL output pairs • Using a 19.53125MHz or 25MHz 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: 490MHz to 680MHz • RMS phase jitter @ 156.25MHz (1.875MHz - 20MHz): 0.53ps (typical) • 3.
