This document describes the SMT340, the SMT360 and the SMT380 TIM ADC from a User' s
perspective.
The SMT340 is a single width TIM-40 compliant module consisting of a dual channel 40MHz, 12-Bit
ADC. Data output is via two Sundance Digital Bus Connectors (SDB). An FPGA on the module controls
various modes of Sampling and Data routing.
The SMT360 is a single width TIM-40 compliant module consisting of a dual channel 65MHz, 12-Bit
ADC. Data output is via two Sundance Digital Bus Connectors (SDB). An FPGA on the module controls
various modes of Sampling and Data routing.
The SMT380 is a single width TIM-40 compliant module consisting of a dual channel 105MHz, 12-Bit
ADC. Data output is via four Sundance Digital Bus Connectors (SDB). An FPGA on the module controls
various modes of Sampling and Data routing.
The SMT340/360/380 makes use of the Analog Devices AD9432 ADC to realise a high speed 12-bit
Analogue to Digital Converter. The SMT380 does not implement any filters in the signal paths, the
analogue signal is buffered with a differential buffer (AD8138) before the ADC samples it (For more
information see the AD9432 and AD8138 datasheets as listed above in Reference Documents).
The module is typically suitable for the following applications
• Communications
• Base stations and ' Zero-IF' Subsystems
• Wireless Local Loop (WLL)
• Local Multipoint Distribution Service (LMDS)
• HDTV Broadcast Cameras and Film Scanners
