The spread-spectrum modulation spreads the clock energy across a wider frequency band, reducing peak EMI at the fundamental and its harmonics by several dB — a practical advantage when the PCB layout has to pass CISPR 25 radiated emissions without a metal shield can. ## 1.7 V to 1.9 V supply, 20-TSSOP package Operating from a single 1.7 V to 1.9 V rail, the CDCE937QPWRQ1 sits on the low-voltage core supply common in automotive infotainment and ADAS processors — no separate 3.3 V clock rail is needed. All seven LVCMOS outputs are non-differential, and the part does not include a divider on the output side — the 1:7 fanout is a straight buffer with spread-spectrum modulation applied to the output clock tree.","metaTitle":"CDCE937QPWRQ1 Clock Driver, 230 MHz, AEC-Q100, TSSOP-20","metaDescription":"Texas Instruments CDCE937QPWRQ1 spread spectrum clock driver, 230 MHz max, 1:7 fanout, LVCMOS I/O, -40 to 125°C, AEC-Q100.
