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.
Active production and compliance
It is ROHS3 compliant, so it meets current European and global environmental requirements for lead-free assembly. The part is supplied in a tube (24-TSSOP package). Confirm the BOM's preferred packaging before ordering.
Package and layout considerations
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.
