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.
