1:10 fanout buffer for LVTTL clock distribution
The Texas Instruments CDCVF2310PWR is a single-ended, non-differential fanout buffer that distributes one LVTTL clock input to ten LVTTL outputs. It handles clock frequencies up to 200 MHz and operates from a 2.3V to 3.6V supply, making it a fit for 2.5V or 3.3V clock trees in industrial and telecom systems. The 24-TSSOP package keeps the footprint compact for dense PCB layouts.
200 MHz ceiling and fanout — what it means for the clock tree
At 200 MHz, this buffer supports most standard LVTTL clock distribution for FPGAs, ASICs, and Ethernet PHYs that run below that frequency. The 1:10 ratio means one oscillator or PLL output can feed ten loads, but you need to account for trace-length matching and per-output termination to maintain signal integrity at the upper end of the range. The non-differential I/O rules out LVPECL or LVDS clock trees—this part is strictly for single-ended LVTTL rails.
Package and temperature grade
Housed in a 24-TSSOP (4.40 mm width) with surface-mount termination, the part is rated for industrial temperature range from -40°C to 85°C. That covers most outdoor, factory-floor, and telecom cabinet environments. The supply range of 2.3V to 3.6V lets it run from a 2.5V or 3.3V rail without an extra regulator.
