200 MHz 1:10 LVTTL clock distribution buffer
The Texas Instruments CDCVF310PWR is a single-circuit fanout buffer that takes one LVTTL clock input and drives ten LVTTL outputs, rated for frequencies up to 200 MHz. It operates from a 2.3 V to 3.6 V supply, covering both 2.5 V and 3.3 V logic rails without needing a separate regulator — a clean fit for mixed-voltage clock trees in telecom line cards, industrial controllers, and test equipment. The 1:10 fanout ratio lets a single oscillator feed multiple downstream PLLs or ASIC reference inputs, but the ten outputs mean the layout engineer needs to manage stub lengths and per-trace impedance to keep edge rates clean at 200 MHz.
Supply range and temperature grade
The 2.3 V to 3.6 V supply range is wide enough to ride through a 3.3 V rail that droops during a cold-crank event, and the -40°C to 85°C industrial temperature rating covers outdoor telecom cabinets, factory-floor automation, and engine-bay-adjacent enclosures. No differential signalling — input and output are single-ended LVTTL only, so this part is for standard CMOS clock trees, not high-speed differential buses like LVPECL or LVDS.
24-TSSOP footprint and supply rails
Housed in a 24-TSSOP (4.40 mm wide, 0.65 mm pitch), the CDCVF310PWR fits on a two-layer board without a dedicated ground plane under the package — though at 200 MHz the output traces should be routed with controlled impedance and the supply decoupled with a 0.1 µF ceramic per VDD pin. The part is surface-mount only; no through-hole equivalent exists in this family.
