Application Information

The TPCE636 is a half-length X4 PCIe compatible

module providing a user configurable Kintex7 FPGA

with 16 ADC input channels and 16 DAC output

channels.

The TPCE636 ADC input channels are based on the

Linear Dual 16-Bit 5Msps Differential LTC2323-16

ADC. The TPCE636 provides 16 ADC channels.

Each of the 16 channels has a resolution of 16bit

and can work with up to 5Msps. The analog input

circuit is designed to allow input voltages up to ±10V

on each input-pin (results in ±20V differential voltage

range).

The TPCE636 DAC output channels are based on

the Dual 16bit AD5547 DAC. Each DAC output is

designed as a single-ended bipolar ±10V analog

output.

For customer specific I/O extension or inter-board

communication, the TPCE636 provides 64 FPGA

I/Os on a back I/O connector and 4 FPGA Multi-

Gigabit-Transceiver on a Samtec FireFly©

connector. Digital back I/O lines can be configured

as 64 single ended LVCMOS25 or as 32 differential

LVDS25 interface.

All front I/O lines such as the ADC interface and

DAC interface are connected to a 98-pin. Samtec

The User FPGA is connected to a 1GB, 32 bit wide

DDR3 SDRAM. The SDRAM-interface uses an

internal Memory Controller of the Kintex-7.
