Overview
Description
The RC31012A Evaluation Board (EVB) is designed to support users evaluating the RC31012A using clock generation in synthesizer mode for PCIe Gen 1-6 compliance or in jitter attenuation mode. When the EVB is connected via USB to the user’s computer running Renesas Integrated Circuit Toolbox (RICBox™) Software, the RC31012A can be configured in various frequencies with best-in-class performance. The RC31012A offers various features with total 8 pairs of differential outputs. Each pair of output can be programmed to LVCMOS style, LVDS style, and LP-HCSL style outputs. There are 5 general purpose input/output (GPIOs) and 4 general purpose input (GPIs) to support output enables, power down, configuration selection, and status outputs. Voltage levels for VDDX, VDDR, VDDA, VDDD, VDDO1, VDDO2, VDDO3, VDDO4, VDDO5, and VDDO6 can be set by jumper. The EVB kit also has a socket to load a configuration from EEPROM.
Features

AI-generated Summary:
Internal capacitance within the VersaClock® 7 (VC7) device is configured using Renesas IC Toolbox software (RICBox). Load capacitance on the crystal is calculated by considering internal stray capacitance (fixed at 8.2pF), external stray capacitance from PCB traces, and adjustable trimming capacitance. The trimming capacitance can be set in 0.42pF steps from 0 to 26.46pF. Bench setup for trimming involves using evaluation boards (RC21008/RC21012 EVBs), frequency counters, and RICBox software to measure and adjust the crystal frequency by tuning load capacitance. The document details step-by-step procedures for hardware setup, software configuration, and frequency measurement to optimize crystal trimming for accurate oscillator performance.
