ZHCSPZ0A february 2022 – june 2023 LMK1D1208I
PRODUCTION DATA
The outputs of the LMK1D1208I can be individually enabled or disabled through the OUTx_EN register field. The disabled state of the outputs is high impedance as this reduces the power consumption and also prevents back-biasing of the devices connected to these outputs. Unused outputs should be disabled to eliminate the need for a termination resistor. In the case of enabled unused outputs, TI recommends a 100-Ω termination for optimal performance.
Table 9-7 describes the control of this function. OUTx_EN is set by register 0x00 (R0). See R0 Register for more information on this register.
