Powered by Altera's Mercury programmable ASSP, Echotek has released the ECTR-114-B transmitter and ECDR-112-B receiver for wideband digital transmission. With >100MHz input and output bandwidths, the Echotek products are suitable for software-defined radio (SDR), signal intelligence, and beam forming applications supported by the Mercury devices.

Echotek designed the ECDR-112-B receiver and ECTR-114-B transmitter to meet the need for an SDR. "We needed 16-bit, 47-tap finite impulse response (FIR) filters running twice as fast as the fastest commercially available ASSPs, and the Mercury devices delivered," said Echotek president Ralph Kimball.

SDR systems provide secure communication by sending and receiving signals throughout the available spectrum, allowing secure signals to be a hidden component within the spectrum.

The ECDR-112-B transmitter is a 12-bit ADC with a sampling rate of 460MSa/s. It is a user-programmable FPGA that offers 16-bit accurate NCO. The ECTR-114-B receiver is a 14-bit DAC that performs 2,4 or 8 interpolations.

The Mercury devices provide up to 18 channels of 1.25Gbps CDR transceiver support for a maximum CDR bandwidth of 45Gbps. Housed in the company's FineLine BGA package, the devices integrate up to 14,400 logic elements and up to 114,000 RAM bits.

The hardware-assisted multipliers within Mercury allow over 30 to 16-by-16 signed or unsigned multiplications with speeds in excess of 300MHz. Their CDR transceivers enable support for high-speed serial backplane applications or for high-data rate communication such as Gigabit Ethernet.
