ICS84330C

700MHz, Low Jitter, Crystal-to-3.3V Differential LVPECL Frequency 84330C DATA SHEET General Description The 84330C is a general purpose, single output high frequency synthesizer. The VCO operates at a frequency range of 250MHz to 700MHz. The VCO and output frequency can be programmed using the serial or parallel interfaces to the configuration logic. The output can be configured to divide the VCO frequency by 1, 2, 4, and 8. Output frequency steps as small as 250kHz to 2MHz can be achieved using a 16MHz crystal depending on the output divider settings. Features Fully integrated PLL, no external loop filter requirements One differential 3.3V LVPECL output Crystal oscillator interface: 10MHz to 25MHz Output frequency range: 31.25MHz to 700MHz VCO range: 250MHz to 700MHz Parallel or serial interface for programming M and N dividers during power-up RMS period jitter: 5ps (maximum) Cycle-to-cycle jitter: 40ps (maximum) 3.3V supply voltage 0°C to 70°C ambient operating temperature Available in lead-free (RoHS 6) package Block Diagram OE Pullup XTAL1 XTAL2 FREF_EXT OSC Pulldown XTAL_SEL Pullup 1 0 ÷ 16 PLL PHASE DETECTOR VCO ÷M ÷2 ÷2 1 ÷4 ÷8 ÷1 0 S_LOAD S_DATA S_CLOCK nP_LOAD Pulldown Pulldown Pulldown Pullup M0:M8 N0:N1 Pullup Pullup 84330C Rev D 4/22/15 CONFIGURATION INTERFACE LOGIC VEE TEST VCC VEE nFOUT FOUT VCC Pin Assignments 25 24 23 22 21 20 19 S_CLOCK 26 18 N1 S_DATA 27 ICS84330C 17 N0 S_LOAD 28 28 Lead PLCC 16 M8 V...
