FemtoClock™ 2 Evaluation Kit
This is the evaluation kit for the RC32514A and RC22514A. The board will come populated with an RC32514. The RC22514 is functionally a subset of the RC32514A, so this...

描述
The RC32514A is a small, low-power timing component designed to be placed immediately adjacent to a PHY, switch, ASIC, or FPGA that requires several reference clocks with a jitter performance of less than 100fs. The RC32514A can act as a frequency synthesizer to locally generate the reference clock, a jitter attenuator to perform local clean-up, and/or frequency translation of a centrally-supplied reference, a synchronous Ethernet equipment clock to perform passband filtering and clean-up of network-supplied references or as a digitally controlled oscillator (DCO) for frequency margining or OTN clock applications. It contains an internal crystal that can be leveraged as the frequency reference for the onboard PLL if desired.
特性
- Jitter below 100fs RMS (10kHz to 20MHz)
- Compliant with ITU-T G.8262 for synchronous Ethernet/OTN (EEC/OEC) and ITU-T G.8262.1 for enhanced synchronous Ethernet/OTN (eEEC/eOEC)
- PLL core consists of fractional-feedback Analog PLL (APLL) which can optionally be steered by a Digital PLL (DPLL)
- Operates from an internal crystal
- APLL frequency independent of input/crystal frequency
- Operates as a frequency synthesizer, jitter attenuator, synchronous equipment slave clock or Digitally Controlled Oscillator (DCO)
- DPLL loop filter programmable from 0.1Hz to 12kHz
- DCO has a tuning granularity of < 1ppb
- Programmable input buffer supports HCSL, LVDS, or two LVCMOS with no external terminations needed
- Input frequencies: 1MHz to 800MHz (250MHz for LVCMOS)
- Reference monitor qualifies/disqualifies input clock
- Programmable status output
- 4 differential/8 LVCMOS outputs
- Any frequency from 10MHz to 1GHz (180MHz for LVCMOS)
- Programmable output buffer supports HCSL (DC-coupled), LVDS/LVPECL/CML (AC-coupled) or two LVCMOS
- Differential output swing is selectable: 400mV to 800mV
- Output clock phase individually adjustable in 100ps steps
- Output Enable input with programmable effect
- Supports up to 1MHz I²C or up to 20MHz SPI serial processor port
- Can configure itself automatically after reset through internal customer-definable One-Time Programmable (OTP) memory with up to four different configurations
- 4mm × 4mm 28-VFQFPN package
