6 / 38 page LMH0366 SNAS585D – APRIL 2012 – REVISED APRIL 2013 www.ti.com DC Electrical Characteristics (continued) Over recommended supply voltage and operating temperature ranges, unless otherwise specified. (1)(2) Symbol Parameter Conditions Reference Min Typ Max Units ICC Supply Current Normal operation, two output 58 75 mA drivers Normal operation, one output driver and low power settings 40 55 mA (5) Device disabled 7 14 mA (ENABLE = 0) (5) Low power mode with one output driver is achieved by powering down the second output driver, setting the amplitude of the active output driver to the lowest setting, disabling input signal detection, and disabling signal detection and equalization for input channels not present on the LMH0366. This can be configured with the following SPI register settings: write “1” to register 0x20 bit 7 (SIG_DET_PRESET) to force the reclocker to assume an input signal is present (so input signal detection can be turned off), write “1” to register 0x11 bit 3 (SDO1_PD) to power down the SDO1 output driver, write “00” to register 0x12 bits 7:6 (SDO0_VOD) to set the SDO0 VOD to 400 mVP-P, and write “11111110” (0xFE) to register 0x15 to power down the input signal detection as well as power down the signal detection and the equalization for input channels not present on the LMH0366.

Typical specifications are estimations only and are not ensured. (2) Typical values represent most likely parametric norms at VCC = +2.5V, TA = +25°C, and at the Recommended Operating Conditions at the time of product characterization and are not ensured. (3) Specification is ensured by characterization and is not tested in production. (4) Peak-to-peak amplitude with sinusoidal modulation per SMPTE RP 184-1996 paragraph 4.1. The test data signal shall be color bars. (5) Refer to “A1” in Figure 1 of SMPTE RP 184-1996.
