Renesas EVK5P35021PROG

Overview

EVK5P35021PROG from Renesas Electronics is a VersaClock® programmable clock generator IC designed for PCIe Gen1–3, consumer electronics, and automotive infotainment systems. It features a three-PLL architecture, six configurable frequency outputs (1 MHz–500 MHz), <1.5 ps RMS differential jitter (12 kHz–20 MHz), and integrated Proactive Power Saving (PPS) for sub-2 µA 32.768 kHz RTC operation.

For engineers reviewing the EVK5P35021PROG datasheet, EVK5P35021PROG pinout, EVK5P35021PROG application, or EVK5P35021PROG equivalent, this evaluation kit enables rapid validation of I2C-programmable clock synthesis, dynamic frequency control (DFC), spread-spectrum EMI reduction, and low-power RTC timing in real-world PCIe and automotive subsystems.

Technical Context

The EVK5P35021PROG is an evaluation platform for the 5P35021 programmable clock generator IC, implementing its full three-PLL architecture with independent VCO tuning, OTP-configurable output formats (LVCMOS/LVDS/LVPECL/LP-HCSL), and hardware-assisted DFC/PPS/ORT functions. It supports all input modes: crystal (8–40 MHz), LVCMOS (1–125 MHz), and differential clock (8–125 MHz).

Key on-board capabilities include selectable power domains (VDD33/VDDA/VBAT), configurable OE1 pin routing for PPS/DFC/PD# functions, dual spread-spectrum sources (analog on PLL1, digital on PLL2), and full I2C register access via SDA_DFC0/SCL_DFC1 headers. The board exposes all 20 pins of the 3×3 mm VFQFPN package for signal probing and custom load testing.

FAQ

What is the primary function of the EVK5P35021PROG evaluation kit?

The EVK5P35021PROG evaluation kit provides a complete, ready-to-use hardware platform for evaluating the Renesas 5P35021 programmable clock generator IC. It enables engineers to validate all key features-including three-PLL frequency synthesis, I2C configuration, DFC switching, PPS low-power mode, spread-spectrum EMI reduction, and multi-format output routing-without custom PCB design. The EVK5P35021PROG directly maps to the 20-pin VFQFPN package and exposes all critical signals for measurement and integration testing.

Does the EVK5P35021PROG support both automotive and industrial temperature grades of the 5P35021 IC?

Yes, the EVK5P35021PROG is designed to operate across the full –40°C to +105°C range and supports both automotive (AEC-Q100 Grade 2) and industrial variants of the 5P35021 IC. Its power delivery, thermal layout, and component selection comply with automotive reliability requirements, allowing direct validation of timing performance under extended temperature conditions specified for the target 5P35021 device.

How is the 32.768 kHz RTC output validated on the EVK5P35021PROG?

The EVK5P35021PROG validates the 5P35021's ultra-low-power 32.768 kHz output by providing dedicated VBAT header pins (2.5–3.3 V), onboard coin-cell socket option, and SE1 test point access. When VBAT is applied and the 5P35021 is configured for DCO mode, the EVK5P35021PROG delivers <2 µA quiescent current while maintaining accurate RTC timing-verified using oscilloscope current probes and frequency counters per the 5P35021 datasheet's VBAT switching threshold specifications.

Can the EVK5P35021PROG demonstrate Dynamic Frequency Control (DFC) with hardware pin control?

Yes, the EVK5P35021PROG supports hardware-based DFC using the OE1 pin as DFC0 control, as defined in the 5P35021 datasheet. Jumpers and test points allow OE1 to be asserted/deasserted to trigger smooth, overshoot-free VCO frequency transitions between up to four pre-programmed PLL2 configurations. Real-time DFC behavior-including ORT activation and timer-synchronized switching-is observable on DIFF1/DIFF2 outputs with spectrum analyzers or jitter analyzers.

What interfaces are available for configuring the 5P35021 IC via the EVK5P35021PROG?

The EVK5P35021PROG provides direct access to the 5P35021's I2C interface via labeled SDA_DFC0 and SCL_DFC1 headers with 4.7 kΩ pull-ups, supporting standard 100 kHz/400 kHz operation. It also exposes all configuration pins-including SEL_DFC, CLKIN/X2, CLKINB/X1, and OE1-for mode selection and external control. No additional adapters or firmware are required to perform full register read/write, OTP programming, or real-time DFC/PPS function testing on the EVK5P35021PROG.
