The differential HCSL signalling keeps edge rates clean for PCIe reference clocks, Ethernet PHY masters, and FPGA reference distribution. ## Industrial temperature and supply range The supply rail accepts 3V to 3.6V, so a nominal 3.3V rail with ±5% tolerance stays inside the window without an extra regulator. ## 48-VQFN package and reflow considerations Housed in a 48-VFQFN with an exposed pad (6x6 mm body), the part requires a thermal land on the PCB to pull heat out of the die. Standard lead-free reflow profile applies; no exotic process steps needed. ## Active production — sourcing posture We source against your BOM quantity and confirm current pricing and lead time at quote — no stock-holding claim, no shelf-life risk.","metaTitle":"CDCDB803RSLR Clock Buffer 1:8 250MHz 48VQFN - Texas","metaDescription":"Texas Instruments CDCDB803RSLR clock buffer, 1:8 fanout, HCSL I/O, 250 MHz max, -40°C to 105°C, 48-VQFN.
