1:2 LVCMOS fanout buffer for general-purpose clock distribution
The Texas Instruments CDC3RL02YFPR is a single-channel fanout buffer that distributes one LVCMOS input to two LVCMOS outputs. It operates from a 2.3 V to 5.5 V supply, making it suitable for mixed-voltage systems where a single buffer needs to bridge a 3.3 V clock source to a 5 V logic input or vice versa, as long as the levels are LVCMOS-compatible. The maximum output frequency is 52 MHz, which covers most microcontroller and FPGA reference clocks, SPI bus clocks, and general-purpose logic timing. The part is non-differential on both input and output (No/No), so it is strictly for single-ended LVCMOS clock trees. The industrial temperature range of -40°C to 85°C allows deployment in outdoor telecom cabinets, factory-floor controllers, and automotive cabin electronics that do not require AEC-Q100 qualification.
52 MHz ceiling and what it means for your clock tree
At 52 MHz, this buffer handles most common clock frequencies for 8-bit and 32-bit MCUs, audio codecs, and low-speed serial interfaces (I2C, SPI, UART). It is not intended for high-speed differential clocks (e.g., LVDS, LVPECL) or RF synthesizers. If your design requires fanout at 100 MHz or above, you would need a different buffer family such as the CDCLVP1204, which handles 2 GHz differential signals.
Package and footprint: 8-DSBGA
The 8-DSBGA package (0.4 mm pitch, 0.8 mm × 1.2 mm body) requires a fine-pitch PCB process. The landing pattern is non-standard for hobbyist boards; expect to use a 4-layer board with micro-vias if routing under the BGA. The part is surface-mount only, and the small footprint saves board area in space-constrained designs like handheld instruments or IoT modules.
Lifecycle and sourcing posture
The CDC3RL02YFPR is listed as Active by Texas Instruments, with ROHS3 compliance. This means it remains a safe choice for new production builds, and there is no last-time-buy pressure. For volume commitments, ask about lead time and factory order support.
