EVM Basic Functions
Eight analog inputs to the ADC are provided via external SMA connectors.
The EVM provides an external SMA connector for input of the ADC clock. The ADC can be clocked using
either a single-ended or differential clock. Provisions are made on the EVM to allow users to evaluate the
ADC using a single-ended PECL clock and a differential transformer-coupled clock.
Digital output from the EVM is via a high-speed, high-density Samtec output header. The digital output
connector mates directly to the TSW1200 Rev B or through an adapter to the TI ADSDeSer-50EVM, both
of which deserialize the serial data stream into parallel CMOS data.
Power connections to the EVM are via banana jack sockets. Separate sockets are provided for the ADC
analog and ADC digital supplies and for the auxiliary circuits.
