1:10 LVTTL clock distribution at 200 MHz
The CDCVF2310PW is a 1:10 fanout buffer from Texas Instruments, accepting a single LVTTL input and delivering ten LVTTL outputs at up to 200 MHz. This part is designed for clock distribution in systems where a single clock source must drive multiple loads without degrading signal integrity. The non-differential I/O (LVTTL in/out) keeps the BOM simple and the layout straightforward — no external termination resistors needed for differential pairs.
Fanout ratio and supply flexibility
With a 1:10 fanout ratio, a single LVTTL clock source can feed ten downstream devices — enough for a moderate clock tree without needing a second buffer stage. The wide supply range (2.3V–3.6V) means the same part can be used across 2.5V and 3.3V domains, reducing inventory complexity.
The part is supplied in a tube (24-TSSOP package). Confirm the BOM's preferred packaging before ordering.
The 24-TSSOP package (0.173-inch body width, 4.40 mm) is a fine-pitch SMD package that requires careful PCB layout. Supply decoupling is critical for clock buffers: place a 0.1 µF ceramic capacitor as close as possible to each supply pin, with a bulk capacitor (10 µF) nearby. The wide supply range (2.3V–3.6V) gives some margin for rail noise, but the output jitter will degrade if the supply is noisy.
