1:8 PLL clock driver for 3.3 V clock trees
The Texas Instruments CDCVF25081D is a single-circuit PLL clock driver with bypass, accepting two LVTTL inputs and delivering eight LVTTL outputs in a 16-SOIC package. It operates from a 3 V to 3.6 V supply and is rated for the industrial temperature range of -40°C to 85°C. The device is designed for clock distribution in systems where a clean, low-jitter clock is needed across multiple loads, such as networking equipment, base stations, and industrial controllers.
200 MHz maximum frequency — clock-tree headroom
The 200 MHz maximum frequency sets the upper bound for the output clock rate.
PLL with bypass — when to use each mode
The PLL includes a bypass mode. In normal operation, the PLL multiplies or cleans up the input clock, providing a frequency- and phase-locked output. In bypass mode, the input clock passes through to the outputs with minimal delay — essentially the device acts as a 1:8 fanout buffer. This is useful during system bring-up, for test modes, or when the input clock is already clean and only fanout is needed. The bypass feature means one BOM line item covers both use cases.
2:8 fanout — driving multiple loads from one device
With a 2:8 input-to-output ratio, the CDCVF25081D can distribute one or two clock sources to up to eight destinations.
Lifecycle and sourcing
The CDCVF25081D is listed as Active and ROHS3 compliant. There is no end-of-life notice or last-time-buy window. The part is available through independent distribution and is sourced to order against an RFQ. For volume commitments or long-term BOM planning, no LTB risk is present.
