描述
This is the evaluation kit for the RC32508A jitter attenuator and clock generator. The board comes populated with an RC32508A device.
特性
- Can be configured as clock generator or jitter attenuator/synchronizer
- Low power, less than 0.8W typical
- Low jitter, less than 50fs-RMS
- Compliant with ITU-T G.8262 & G.8262.1 option 1 and 2 for synchronous Ethernet Equipment Clock (EEC/eEEC) without degrading output jitter
- Jitter attenuation with programmable loop bandwidth from 0.1Hz to 12kHz
- Up to 2 independent frequency domains and 8 integer output dividers
- Each frequency domain can be slaved with DPLL or free-run
- DPLL can be configured as DCO
- LVCMOS, AC-LVPECL, AC-LVDS, HCSL, AC-CML output modes supported with programmable output swing
- Up to 2single ended or 1differential clock inputs, 1 crystal/XO/TCXO/OCXO input
- Supports 1MHz I2C, 400kHz SMBus or 50MHz SPI serial port
- Internal non-volatile memory (up to 8 different configurations) provides default device settings on power-up.
- 1.8V core and output operation
- -40°C to +85°C industrial temperature operation

AI 生成的摘要:
The FemtoClock 2 clock generator configures synchronous Ethernet (SyncE) clocks with jitter attenuation to meet ITU-T G.8262 requirements. It supports two SyncE options for 2048Kbps and 1544Kbps hierarchies and an enhanced SyncE option (G.8262.1). Configuration uses Renesas IC Toolbox (RICBox) software, enabling easy selection of SyncE profiles and jitter attenuator settings. The recommended device, RC32504A, requires a stable frequency reference like a TCXO instead of a quartz crystal. The document details software setup, configuration steps, and compliance testing for SyncE applications.
