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.
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.
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.
