Selecting Clock Mode
The MAX1061/MAX1063 operate with either an internal
or an external clock. Control bits D6 and D7 select
either internal or external clock mode. The parts retain
the last-requested clock mode if a power-down mode is
selected in the current input word. For both internal and
external clock modes, internal or external acquisition
can be used. At power-up, the MAX1061/MAX1063
enter the default external clock mode.
Internal Clock Mode
Select internal clock mode to release the P from the
burden of running the SAR conversion clock. To select
this mode, bit D7 of the control byte must be set to 1
and D6 must be set to zero. The internal clock frequen-
cy is then selected, resulting in a conversion time of
3.6s. When using the internal clock mode, tie the CLK
pin either high or low to prevent the pin from floating.
External Clock Mode
To select the external clock mode, bits D6 and D7 of
the control byte must be set to 1. Figure 6 shows the
clock and WR timing relationship for internal (Figure 6a)
and external (Figure 6b) acquisition modes with an
external clock. For proper operation, a 100kHz to
4.8MHz clock frequency with 30% to 70% duty cycle is
recommended. Operating the MAX1061/MAX1063 with
clock frequencies lower than 100kHz is not recom-
mended, because it causes a voltage droop across the
hold capacitor in the T/H stage that results in degraded
performance.
Digital Interface
Input (control byte) and output data are multiplexed on
a tri-state parallel interface. This parallel interface (I/O)
can easily be interfaced with standard Ps. The signals
CS, WR, and RD control the write and read operations.
CS represents the chip-select signal, which enables a
P to address the MAX1061/MAX1063 as an I/O port.
When high, CS disables the CLK, WR, and RD inputs
and forces the interface into a high-impedance (high-Z)
state.
Input Format
The control byte is latched into the device on pins
D7–D0 during a write command. Table 2 shows the
control byte format.
Output Format
The output format for both the MAX1061/MAX1063 is
binary in unipolar mode and two’s complement in bipo-
lar mode. When reading the output data, CS and RD
must be low. When HBEN = 0, the lower 8 bits are
read. With HBEN = 1, the upper 2 bits are available
and the output data bits D7–D2 are set either low in
unipolar mode or set to the value of the MSB in bipolar
mode (Table 5).
