Texas Instruments CDCE906-706PROGEVM

Overview

CDCE906-706PROGEVM from Texas Instruments is an evaluation module for the CDCE906 programmable 3-PLL clock synthesizer, designed to validate timing architectures in video/audio systems and embedded digital interfaces. It supports crystal (8–54 MHz), LVCMOS, or differential clock inputs; delivers six independent LVCMOS outputs up to 167 MHz; and enables in-system SMBus programming of PLL dividers (M=1–511, N=1–4095), post-dividers (1–127), slew-rate control, and spread-spectrum clocking (SSC) for EMI reduction.

For engineers reviewing the CDCE906-706PROGEVM datasheet, CDCE906-706PROGEVM pinout, CDCE906-706PROGEVM application, or CDCE906-706PROGEVM equivalent, this module provides hands-on validation of zero-ppm clock synthesis, multi-output frequency agility, SSC modulation depth selection (±0.1% to ±0.4%), and EEPROM-based configuration persistence across power cycles - critical for HDMI, audio codec, and FPGA clock tree development.

Technical Context

The CDCE906-706PROGEVM implements a full reference design for the CDCE906 IC, featuring three independent PLLs - PLL1 and PLL3 optimized for zero-ppm precision, and PLL2 supporting center-spread and down-spread SSC modulation. Each PLL integrates programmable reference (M) and feedback (N) dividers, with VCO frequency range selectable between 80–200 MHz (normal mode) or 180–300 MHz (high-speed mode).

The module routes all six LVCMOS outputs (Y0–Y5) through a 6×6 programmable switching matrix with per-output 7-bit post-divider, inversion logic, and four-level slew-rate control. Power delivery separates VCCOUT1 (Y0/Y1) and VCCOUT2 (Y2–Y5), supporting 2.3–3.6 V output supply rails independently to optimize drive strength and EMI behavior.

FAQ

What is the primary purpose of the CDCE906-706PROGEVM?

The CDCE906-706PROGEVM is an evaluation module designed exclusively to demonstrate and validate the functionality of the CDCE906 programmable 3-PLL clock synthesizer IC. It provides immediate access to all six LVCMOS outputs, dual clock inputs, SMBus programming interface, and onboard power regulation - enabling rapid characterization of zero-ppm synthesis, SSC modulation, and output switching matrix behavior without custom PCB design. The CDCE906-706PROGEVM does not function as a production clock source itself.

Does the CDCE906-706PROGEVM include the CDCE906 IC pre-installed?

Yes, the CDCE906-706PROGEVM comes with the CDCE906 IC already mounted in its native TSSOP-20 (PW) package and fully soldered onto the evaluation board. No additional assembly or IC sourcing is required to begin testing. All signal routing, decoupling, and SMBus pull-up networks are implemented per TI's recommended layout guidelines to ensure accurate performance measurement of the CDCE906 IC.

Can the CDCE906-706PROGEVM generate spread-spectrum clocking (SSC)?

Yes - the CDCE906-706PROGEVM enables SSC functionality through the onboard CDCE906 IC, which supports both center-spread (±0.1%, ±0.25%, ±0.4%) and down-spread (1%, 1.5%, 2%, 3%) modulation modes exclusively on PLL2. This capability is configured via SMBus register writes (Byte 25) and verified using oscilloscope spectral analysis or jitter analyzers. The CDCE906-706PROGEVM provides direct test points for monitoring modulated outputs Y0–Y5.

What software tools are required to program the CDCE906 on the CDCE906-706PROGEVM?

Texas Instruments' Pro-Clock™ software is the official GUI tool for configuring the CDCE906 IC on the CDCE906-706PROGEVM. It supports real-time register editing, PLL frequency calculation, SSC parameter setup, EEPROM programming, and configuration export/import. The CDCE906-706PROGEVM connects via USB-to-SMBus adapter (not included), and Pro-Clock™ communicates directly with the CDCE906's SMBus interface (SCLOCK/SDATA pins) to read/write all 27 registers including M/N dividers, post-dividers, and slew-rate settings.

Is the CDCE906-706PROGEVM suitable for production use in end equipment?

No - the CDCE906-706PROGEVM is strictly an evaluation and development tool, not a production-grade component. Its layout, thermal design, and component selection prioritize debug visibility and flexibility over long-term reliability, EMC compliance, or volume manufacturability. For production deployment, designers must integrate the CDCE906 IC into their own board using TI's layout guidelines, validated power sequencing, and appropriate filtering. The CDCE906-706PROGEVM serves only to de-risk that integration path.
