www.ti.com SNAS600A – JULY 2012 – REVISED MARCH 2013 LM97600 7.6-Bit, 1/2/4 Channel, 5/2.5/1.25 GSPS, High Performance, Low Power A/D
Converter
Check for Samples: LM97600 FEATURES DESCRIPTION The LM97600 is a single/dual/quad, low power, high
performance
SiGe
BiCMOS
analog-to-digital
converter that digitizes signals at sampling rates up to
5.0/2.5/1.25 GSPS. Consuming a typical 3.1 Watts at
5 GSPS from 1.2 and 2.5 Volt dual supplies, this
device is ensured to have no missing codes over the
full operating temperature range. The unique folding
and interpolating architecture, the fully differential
comparator design, the innovative design of the
internal sample-and-hold amplifier and the selfcalibration scheme enable an excellent response of
all dynamic parameters, producing a high 6.6
Effective Number Of Bits, (ENOB) with a 248 MHz
input signal and a 5 GHz sample rate. The LM97600
achieves a 5 GSPS sampling rate by utilizing both the
rising and falling edge of a 2.5 GHz input clock. Data
encoding is 8 bits offset binary. Average output word
size is 7.6 bits. The serialized data is 8b10b encoded …
