CDCE421AEVM是CDCE421A的评估模块。 CDCE421A是一个高度灵活,<1ps的RMS的超低抖动频率合成器,采用低频晶体或LVCMOS输入并产生输出时钟从10MHz至1100MHz与完全集成的硅的VCO。DescriptionCDCE421AEVM is the evaluation module for CDCE421A. CDCE421A is a highly versatile, <1ps rms ultra low-jitter frequency synthesizer that takes a low-frequency crystal or LVCMOS input and generates clock output from 10MHz to 1100MHz with fully integrated silicon VCO. The output is selectable among LVPECL, LVDS, or 2 LVCMOS. It is intended to replace high frequency XO for a variety of wireline and data communication applications. Features
- Integrated Crystal Oscillator Circuitry with Integrated Frequency Synthesizer
- Low Output Jitter: 380 fs RMS typical (from 10 kHz to 20 MHz); Low Phase Noise at High Frequency (708-MHz LVPECL): Typically -109 dBc/Hz at 10 kHz and -146dBc/Hz at 10 MHz from the carrier
- Supports Crystal or LVCMOS Input Frequencies from 27.35 MHz to 38.33 MHz
- Output Frequency Ranges from 10.9 MHz to 766.7 MHz and from 875.2 MHz to 1175 MHz
- Fully Integrated Programmable Loop Filter
- Integrated On-Chip Nonvolatile Memory (EEPROM) Stores Settings Without Applying High Voltage
- 4-mm X 4-mm QFN-24 Package
- Industrial Temperature Range: -40°C to +85°C
- Single Supply at 3.3 V
