CONVERTER OPERATION
TheLTC2258-12/LTC2257-12/LTC2256-12arelowpower
12-bit 65Msps/40Msps/25Msps A/D converters that are
poweredbyasingle1.8Vsupply.Theanaloginputsshould
be driven differentially. The encode input can be driven
differentially or single-ended for lower power consump-
tion. The digital outputs can be CMOS, double data rate
CMOS (to halve the number of output lines), or double
data rate LVDS (to reduce digital noise in the system.)
Many additional features can be chosen by programming
the mode control registers through a serial SPI port. See
the Serial Programming Mode section.
ANALOG INPUT
The analog input is a differential CMOS sample-and-hold
circuit (Figure 2). The inputs should be driven differentially
around a common mode voltage set by the VCM output
pin, which is nominally VDD/2. For the 2V input range,
the inputs should swing from VCM – 0.5V to VCM + 0.5V.
