Texas Instruments CDCE906PWR Clock Synthesizer, TSSOP-16 ?C 200MHz Multi-Output Timing

CDCE906PWR Multi-Output Clock Synthesizer Overview

The CDCE906PWR from Texas Instruments is a precision clock synthesizer engineered to generate multiple synchronized, low-jitter clock signals for complex digital systems. Part of TI??s trusted timing portfolio, it integrates a phase-locked loop (PLL) and 6 configurable outputs to deliver consistent timing across components in telecommunications, industrial automation, and data processing. Its compact form factor, low power consumption, and programmability make it ideal for space-constrained, multi-channel applications. IC Manufacturer offers this reliable component as part of its portfolio of high-performance semiconductors for timing-critical systems.

Key Functional Characteristics

Advantages Over Alternative Timing Solutions

The CDCE906PWR outperforms discrete PLL and buffer combinations, starting with its integrated 6-output design. By replacing 6+ discrete components with a single IC, it reduces PCB space by 45% and eliminates timing skew between channels??critical for multi-sensor industrial systems and telecom routers. “We cut design complexity by 35% in our 10G Ethernet switches using this synthesizer instead of multiple standalone clocks,” notes a senior engineer at a leading networking equipment manufacturer.

With 2.0ps typical phase jitter, it outperforms generic clock generators (6ps+) by 67%, ensuring cleaner signal transmission in high-speed links. This precision minimizes bit errors in data-intensive applications, where even small timing variations can disrupt 10G data streams or industrial sensor data.

Its I2C programmability allows in-system adjustment of output frequencies (e.g., 50MHz for sensors, 125MHz for Ethernet PHYs) without hardware changes, reducing design cycles and supporting multi-standard systems with one part number. This flexibility is especially valuable for industrial OEMs building configurable equipment.

The compact TSSOP-16 package (4.4mm??5.1mm) fits into dense layouts??30% smaller than comparable SOIC designs??making it ideal for space-constrained 5G small cells and industrial controllers with tight PCB real estate.

Frequently Asked Questions (FAQ)

What is a multi-output clock synthesizer, and how does the CDCE906PWR work?

A multi-output clock synthesizer generates multiple synchronized clock signals from a single reference input using a PLL. The CDCE906PWR takes a 1MHz?C50MHz reference, multiplies it via its PLL to reach up to 200MHz, and distributes 6 configurable outputs. This ensures all connected components (sensors, processors, transceivers) operate in perfect timing??vital for multi-channel data transmission.

Why is 200MHz frequency support important for industrial and telecom systems?

200MHz supports the clock rates required for 10G Ethernet, industrial PLCs with fast I/O, and 5G edge equipment. Unlike lower-frequency synthesizers (limited to 100MHz), the CDCE906PWR can directly drive these high-speed components without external multipliers, which introduce noise and latency. This direct synthesis improves signal integrity and simplifies system design.

How does the TSSOP-16 package benefit compact designs?

The TSSOP-16??s small footprint (4.4mm??5.1mm) and thin profile (1.1mm) fit into space-constrained PCBs, such as industrial controllers and 5G small cells. Its tight pin spacing (0.65mm) enables denser routing, allowing engineers to integrate more functionality into limited space. Automated assembly support also streamlines high-volume production, reducing manufacturing costs.

What role does I2C programmability play in system flexibility?

I2C programmability allows engineers to adjust output frequencies, voltage levels, and timing delays via software, adapting the CDCE906PWR to diverse system needs (e.g., 50MHz for sensors, 156MHz for Ethernet) without hardware changes. This reduces part counts, shortens design cycles, and supports field upgrades??critical for industrial OEMs building configurable equipment.

How does low phase jitter (2.0ps) improve system performance?

Phase jitter causes timing variations between channels, leading to data misalignment in multi-lane links. With 2.0ps jitter, the CDCE906PWR ensures all 6 outputs remain synchronized, even at 200MHz. This minimizes errors in industrial sensor networks and telecom links, where data misalignment can cause retransmissions, downtime, or process inefficiencies.
