2Gs/s Dual Track-and-Hold, TH723

2Gsps Dual-Stage Differential Track-and-Hold
TH723
PRODUCT DESCRIPTION
TH723 is a dual-stage differential Track-and-Hold amplifier with independent clock
inputs. TH723 is able to sample 2 GHz signal with 11 bits of resolution, making it anideal solution for high-speed high-resolution data acquisition systems like
instrumentation, radio, radar, tester, etc.

KEY FEATURES• > 9 GHz small-signal bandwidth• > 8 GHz large-signal bandwidth (1 Vp-p differential)• 200-2000 MHz sampling rate
• -70 dB THD (single-ended 250mVp-p 2GHz input)• -59 dB THD (single-ended 250mVp-p 4GHz input)• -56 dB THD (single-ended 250mVp-p 6GHz input)• < 70 fs aperture jitter• < 200 ps acquisition time
• < 30 ps rise time (20-80%)• Differential analog input/output• Excellent performance with single-ended input• Adjustable output common mode voltage• Independent track mode enable on both stages

TYPICAL CONNECTION DIAGRAM

Description:
The measurements in the TH723 data sheet were taken using the setup above. First, connect the output OP
to a spectrum analyzer and output ON to an oscilloscope. Then, connect the differential analog input to IPand IN. Connect the clock frequency to CK1P and CK2N. Terminate the unconnected SMA connectors
with a 50Ω termination caps. After the SMA connections are properly made, connect power supply outputs
to the corresponding DC pins without turning on the power. When ready to use, supply a DC voltage of+5.0V to VCC, +2.0V to VTO, and –5.2V to VEE.
Notes:-Using appropriate band-pass filters for the input signal may improve performance.
