SNAS636C December 2013 – July 2021 LMK00338
The LMK00338 has a 3.3-V core power supply (VCC) and 3 independent 3.3-V or 2.5-V output power supplies (VCCOA, VCCOB, VCCOC). Output supply operation at 2.5 V enables lower power consumption and output-level compatibility with 2.5-V receiver devices. The output levels for HCSL are relatively constant over the specified VCCO range. Refer to Section 9 for additional supply related considerations, such as power dissipation, power supply bypassing, and power supply ripple rejection (PSRR).
Take care to ensure the VCCO voltages do not exceed the VCC voltage to prevent turning-on the internal ESD protection circuitry.
