CM2030

The CM2030’s bi-directional slew rate limiting is integrated into the CEC level-shifter functionality thus allowing

the designer to directly interface a simple low voltage CMOS GPIO directly to the CEC bus and simultaneously

guarantee meeting all CEC output logic levels and HDMI slew-rate and isolation specifications (See Figure 5).

The CM2030 also includes an internal backdrive protected static pullup 120µA current source from the

CE_SUPPLY rail in addition to the dynamic slew rate control circuitry.
