FemtoClock 2 评估套件
这是用于 RC32504A 和 RC22504A 使用点抖动衰减器和时钟发生器的评估套件。 该电路板装有一个 RC32504A 器件。 RC22504A 在功能上是 RC32504A 的子集，因此该板可用于评估两者中的任意一种或两种器件。 有关产品的更多详细信息，请参阅设备页面。
概览
描述
The RC22504A 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 jitter performance less than 100fs (max). The RC22504A can act as a frequency synthesizer to locally generate the reference clock or as a DCO for frequency margining or OTN clock applications.
特性
- Jitter below 100fs RMS maximum (10Hz to 20MHz)
- PLL core consists of fractional-feedback Analog PLL (APLL)
- Operates from a 25MHz to 80MHz crystal or XO
- APLL frequency independent of input / crystal frequency
- Operates as a frequency synthesizer or Digitally Controlled Oscillator (DCO)
- DCO has tuning granularity of < 1ppb
- 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 via internal customer-definable One-Time Programmable (OTP) memory with up to four different configurations
- 4 × 4 mm 24-VFQFPN package
