External Clock Mode
To select 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 7.6MHz clock
frequency with 30% to 70% duty cycle is recommended.
Operating the MAX1294/MAX1296 with clock frequen-
cies lower than 100kHz is not recommended because
the resulting voltage droop across the hold capacitor in
the T/H stage degrades performance.
Digital Interface
The input and output data are multiplexed on a three-
state parallel interface (I/O) that can easily be inter-
faced 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 MAX1294/MAX1296 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.
