7.4 Device Functional Modes
The LMH0395 supports two modes of operation. In pin mode, the LMH0395 operates with control pins to set its
operating state. In SPI mode, an optional SPI serial interface can be used to access and configure multiple
LMH0395 devices in a daisy-chain configuration.
This allows users to program the output common-mode voltage and swing, output de-emphasis level, input
launch amplitude, and power management settings. Users may also access a cable length indicator and all pin
mode features.
7.4.1 Auto Sleep
The auto sleep mode allows the LMH0395 to power down when no input signal is detected. If the AUTO SLEEP
pin is set high, the LMH0395 goes into a deep power-save mode when no signal is detected. The device powers
on again once an input signal is detected. If the AUTO SLEEP pin is set low, the LMH0395 will always be on and
will not enter power-save mode. The auto sleep functionality can be turned off by setting AUTO SLEEP low or
tying this pin to ground. An additional auto sleep setting available in SPI mode can be used to force the equalizer
to power down regardless of whether there is an input signal or not. Auto sleep has precedence over mute and
bypass modes.
In auto sleep mode, the time to power down the equalizer when the input signal is removed is less than 200 µs
and should not have any impact on the system timing requirements. The device will wake up automatically once
an input signal is detected, and the delay between signal detection and full functionality of the equalizer is
negligible (about 5 ms). The overall system will be limited only by the settling time constant of the equalizer
adaptation loop.
7.5 Programming
7.5.1 SPI Register Access
Setting SPI_EN high enables the optional SPI register access mode. In SPI mode, the LMH0395 provides
register access to all of its features along with a cable length indicator, programmable output de-emphasis,
programmable output common-mode voltage and swing, digital MUTEREF, and launch amplitude optimization.
There are eight supported 8-bit registers in the device (see Table 1). The LMH0395 supports SPI daisy-chaining
among an unlimited number of LMH0395 devices.
7.5.1.1 SPI Transaction Overview
Each SPI transaction to a single device is 16-bits long. The transaction is initiated by driving SS low, and
completed by returning SS high. The 16-bit MOSI payload consists of the read/write command (“1” for reads and
“0” for writes), the seven address bits of the device register (MSB first), and the eight data bits (MSB first). The
LMH0395 MOSI input data is latched on the rising edge of SCK, and the MISO output data is sourced on the
falling edge of SCK.
