Housed in a 48-WFQFN with an exposed pad (7x7 mm), the thermal and ground plane on the PCB directly affect the PLL's phase-noise floor—a solid via array under the pad is non-negotiable for rated jitter performance. ## Input flexibility, output fixed to LVPECL The input stage accepts LVCMOS, LVDS, or LVPECL levels, but the four outputs are LVPECL only—any downstream logic family requires external level translation or AC-coupling. The 1:4 fanout is differential on both sides, meaning each output pair delivers a true complementary clock with controlled edge rates suitable for driving high-speed ADC/DAC or SERDES reference inputs. A divider is present on-chip, but there is no multiplier—the part conditions and fans out a clock, it does not synthesize a higher frequency from a lower reference. ## Industrial temperature band and supply tolerance The supply range is 3.15V to 3.45V—tight enough that supply noise couples directly into the VCO phase noise; a low-noise LDO feeding this rail is standard practice in a jitter-sensitive layout.","metaTitle":"TI LMK03002ISQX/NOPB Clock Conditioner, 1.724GHz, Active","metaDescription":"Texas Instruments LMK03002ISQX/NOPB clock conditioner with PLL, 1.724GHz max, 1:4 LVPECL fanout, -40°C to 85°C.
