LM97600  
7.6-Bit, 1/2/4 Channel, 5/2.5/1.25 GSPS, High Performance, Low Power  
A/D Converter  
General Description  
Features  
The LM97600 is a single/dual/quad, low power, high perfor-  
mance SiGe BiCMOS analog-to-digital converter that digi-  
tizes 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 guaranteed to have no miss-  
ing codes over the full operating temperature range. The  
unique folding and interpolating architecture, the fully differ-  
ential comparator design, the innovative design of the internal  
sample-and-hold amplifier and the self-calibration scheme  
enable an excellent response of all dynamic parameters, pro-  
ducing a high 6.6 Effective Number Of Bits, (ENOB) with a  
248 MHz input signal and a 5 GHz sample rate while providing  
a 10-TBD Word Error 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. Av-  
erage output word size is 7.6 bits. The serialized data is 8b10b  
encoded providing DC balance and AC coupling capability.  
Decoding can be accomplished using existing FPGA serial I/  
O modules.
