Renesas 5P49V6975-PROG

Overview

5P49V6975-PROG from Renesas Electronics is a dedicated programmer board for configuring and programming blank 5P49V6975 VersaClock® 6E programmable clock generators. It features an on-board USB-to-I²C bridge (FTDI chip), a 25 MHz crystal reference (bypassed for 5P49V6975 due to its integrated crystal), socketed DUT interface, and configurable jumpers for SEL0/SEL1, CLKSEL, OE, VDDO outputs, and I²C/SCL/SDA routing. It enables OTP memory programming and volatile register configuration via the Renesas IC Toolbox (RICBox) GUI.

For engineers reviewing the 5P49V6975-PROG datasheet, 5P49V6975-PROG pinout, 5P49V6975-PROG application, or 5P49V6975-PROG equivalent, this board supports full evaluation of 5P49V6975 device behavior-including multi-configuration hardware-select mode validation, differential output waveform measurement (HCSL/LVPECL), and system-level I²C integration testing-prior to final PCB integration.

Technical Context

The 5P49V6975-PROG board implements a direct USB-powered interface between a host PC and the target 5P49V6975 IC using an FTDI-based USB-to-I²C bridge. It provides configurable jumper-based control over SEL0/SEL1 (for hardware configuration selection), CLKSEL (clock source selection), and SD/OE (output enable), all mapped to physical pins on the 5P49V6975 socket per its 25-pin QFN package.

It supports both I²C programming mode (default, JP1 open) and Hardware Select mode (JP1 closed), with on-board 3.3 V regulation for VDDO outputs and SMA-compatible test points (J1, J2, J3) for external reference clock injection or differential output probing. The board's schematics confirm direct pin-to-pin connectivity between U4 (DUT socket) and all labeled test points and jumpers without signal conditioning.

FAQ

What is the primary function of the 5P49V6975-PROG board?

The 5P49V6975-PROG board is a dedicated programmer and evaluation platform for the Renesas 5P49V6975 VersaClock® 6E clock generator. It enables full configuration of volatile registers and one-time programming (OTP) of up to four frequency configurations via the Renesas IC Toolbox (RICBox) GUI. Its design supports both I²C-based development and post-programming hardware-select mode validation using SEL0/SEL1 pins - critical for verifying boot-time clock behavior before system integration.

Does the 5P49V6975-PROG board require an external crystal when used with the 5P49V6975 device?

No. The 5P49V6975 integrates a factory-trimmed crystal oscillator, making the on-board 25 MHz crystal and associated J1/JP17 circuitry inactive for this device. As confirmed in the User Guide, "The 5P49V6975 has an integrated crystal and therefore, J1 / JP17 have no function." The 5P49V6975-PROG board automatically accommodates this by routing power and control signals directly to the DUT socket without reference clock dependency.

How does the 5P49V6975-PROG support differential output verification for HCSL and LVPECL signals?

The 5P49V6975-PROG provides four 2×2 test point banks (JP7, JP9, JP10, JP11) directly connected to the 5P49V6975's CLK1–CLK4 differential output pins. Each bank exposes both signal and ground pins - enabling single-ended probing with standard oscilloscope probes or true differential measurement with matched probes. No internal termination or biasing is applied, preserving signal integrity for accurate swing and jitter assessment per HCSL/LVPECL specifications.

Can the 5P49V6975-PROG be used to program other VersaClock devices besides the 5P49V6975?

Yes - the 5P49V6975-PROG board is backward compatible with earlier VersaClock generations. Using appropriate personality files in RICBox, it supports programming of 5P49V6965 (VC6E), 5P49V6901/6913/6914 (VC6), and multiple VC5-series devices including 5P49V5901 through 5P49V5935. However, the board's default configuration and documentation focus exclusively on the 5P49V6975-PROG and 5P49V6965-PROG variants.

What is the role of JP1 on the 5P49V6975-PROG board?

JP1 selects the operational mode of the 5P49V6975-PROG board at power-up. With JP1 open (no jumper), the board enters I²C Mode - allowing RICBox to communicate with the 5P49V6975 for register read/write and OTP programming. With JP1 closed (jumper installed), the board boots into Hardware Select Mode, where SEL0 and SEL1 pins determine which pre-programmed configuration loads - essential for validating field-boot behavior without host software intervention.
