Dual 1.1Gbps Pin Electronics with Integrated
PMU and Level-Setting DACs
The integration of DCL and PMU functions in the
MAX9979 requires defined states to manage the inter-
action of these resources. The PMU controls supersede
those of the DCL, as described below and shown in
Table 1. Important details to keep in mind are:
? Normal high-speed DCL operation is intended only
when the PMU is in the FNMN state and the DCL is
available, as indicated by Note B in Table 1.
? Forcing LLEAKP_ = 0 immediately places the DCL
into low-leak mode, and the PMU into its high-
impedance state independent of any other pro-
grammed control bit or external control inputs.
Forcing LLEAKP_ = 1 is required to allow any other
mode of operation.
? Forcing HIZFORCE_ = 1 enables the PMU and
simultaneously forces the DCL into low-leak mode.
? Additional PMU settings such as the force and mea-
sure modes, current range, the measure output,
comparators, and the clamp features are controlled
as described later in this document.
? The MAX9979 provides calibration modes under
which both the DCL and the PMU are simultaneously
active. Forcing HIZFORCE_ = 0 ordinarily disables
the PMU, however, when LLEAKS_ is not asserted,
the FMODE_ and MMODE_ bits select these calibra-
Table 1. MAX9979 Mode Selection
tion modes. While in a calibration mode, the DCL
states are still selected by the controls normally
associated with those functions. When in a calibra-
tion mode, the PMU range A is not available. The
PMU range defaults to range B if the serial-interface
bit RS2_ = 1.
Driver
The driver uses a high-speed multiplexer to select one
of three DAC voltages (DHV_, DLV_, and DTV_), or to
select high-impedance mode. Multiplexer switching is
controlled by high-speed differential inputs
DATA_/NDATA_ and RCV_/NRCV_ and mode-control
bit TMSEL_ (see Table 2). The multiplexer output is
buffered to drive DUT_. A programmable slew-rate cir-
cuit controls the slew rate of the buffer input.
In high-impedance mode, the clamps and comparators
remain connected to DUT_, the DUT_ bias current is
less than ±2μA, and the node continues to track high-
speed signals. In low-leakage mode, the bias current at
DUT_ is further reduced to less than ±10nA, yet signal
tracking slows.
The nominal driver output resistance is 50 Ω and fea-
tures an adjustment range of ±2.5 Ω through the serial
interface in 360m Ω increments. Contact the factory for
different output resistance values.
