Merkmale

KI-Übersetzung
  • ITU-T G.813/G.8262 compliance (options 1 & 2)
  • Programmable bandwidth, 0.1Hz to 500Hz
  • Attenuates jitter up to several UI
  • Freerun or holdover on loss of all inputs
  • Hitless reference switching
  • High-resolution holdover averaging
  • Digitally controlled phase adjustment
  • Three inputs, two differential/CMOS, one CMOS
  • Any input frequency from 8kHz to 1250MHz (8kHz to 300MHz for CMOS)
  • Per-input activity and frequency monitoring
  • Automatic or manual reference switching
  • Any output frequency from < 1 Hz to 1035MHz
  • High-resolution fractional frequency conversion with 0ppm error
  • Encapsulated design requires no external VCXO or loop filter components
  • Output jitter as low as 0.25ps RMS (12kHz - 20MHz integration band)
  • Outputs are CML or 2xCMOS, can interface to LVDS, LVPECL, HSTL, SSTL and HCSL
  • In 2xCMOS mode, the P and N pins can be different frequencies (e.g. 125MHz and 25MHz)
  • Per-output supply pin with CMOS output voltages from 1.5V to 3.3V
  • Precise output alignment circuitry and per output phase adjustment
  • Per-output enable/disable and glitchless start/stop (stop high or low)
  • Automatic self-configuration at power-up from internal EEPROM; up to four configurations pin-selectable
  • Numerically controlled oscillator mode
  • Input-to-output alignment with external feedback
  • SPI or I²C processor Interface
  • Easy-to-use evaluation software
  • Very high-resolution DPLL architecture
  • State machine automatically transitions between tracking and freerun/holdover states
  • Revertive or nonrevertive reference selection algorithm
  • Less than 0.1dB gain peaking
  • Programmable phase-slope limiting
  • Programmable tracking range (i.e. hold-in range)
  • Truly hitless reference switching with < 200μs output clock phase transient
  • Output phase adjustment in 10ps steps
  • High-resolution frequency and phase measurement
  • Fast detection of input clock failure and transition to holdover mode
  • Holdover frequency averaging with programmable averaging time and delay time
  • Very high-resolution fractional scaling (i.e. non-integer multiplication)
  • Any-to-any frequency conversion with 0ppm error
  • Two high-speed dividers (integers 4 to 15, half divides 4.5 to 7.5)
  • Easy-to-configure, completely encapsulated design requires no external VCXO or loop filter components
  • Bypass mode supports system testing
  • Three low-jitter output clocks
  • Each output can be one differential output or two CMOS outputs
  • Output clocks can be any frequency from 1Hz to 1035MHz (250MHz max for CMOS and HSTL outputs)
  • In CMOS mode, an additional divider allows the OCxN pin to be an integer divisor of the OCxP pin
  • Outputs easily interface with CML, LVDS, LVPECL, HSTL, SSTL, HCSL and CMOS components
  • Sophisticated output-to-output phase alignment
  • Per-output phase adjustment with high resolution and unlimited range
  • Per-output enable/disable
  • Per-output glitchless start/stop (stop high or low)
  • SPI or I²C serial microprocessor interface
  • Automatic self-configuration at power-up from internal EEPROM memory; pin control to specify one of four stored configurations
  • Numerically controlled oscillator (NCO) behavior allows system software to steer DPLL frequency with resolution better than 0.01ppb
  • Input-to-output alignment with external feedback
  • Four general-purpose I/O pins each with many possible status and control options
  • Output frame sync signals: 2kHz or 8kHz (SONET/SDH), 1Hz (IEEE 1588) or other frequency
  • Internal compensation for local oscillator frequency error
  • Simple, intuitive Windows-based graphical user interface
  • Supports all device features and register fields
  • Makes lab evaluation of the ZL30622 quick and easy
  • Generates configuration scripts to be stored in internal EEPROM
  • Generates full or partial configuration scripts to be run on a system processor
  • Works with or without a ZL30622 evaluation board
