12-Bit, 170Msps ADC

LTM2220-AA
12-Bit, 170Msps ADC
FEATURES
DESCRIPTION
The LTM
®
2220-AA is a 170Msps sampling 12-bit A/D
converter designed for digitizing high frequency, wide
dynamic range signals. The LTM2220-AA is perfect for
demanding communications applications with AC per-
formance that includes 66.2dB SNR and 84dB spurious
free dynamic range.
DC specs include ±0.5LSB INL (typ), ±0.3LSB DNL (typ)
and no missing codes over temperature.
The CLK+ and CLK- inputs may be driven differentially or
single ended with a sine wave, PECL, TTL or CMOS inputs.
A clock duty cycle stabilizer allows high performance at
full speed for a wide range of clock duty cycles.
The LTM2220-AA is pin compatible with the AD9430 when
used with LVDS outputs, 2’s complement output format
and the 1.536V
PP
input range.
