High IF Receiver Reference

Design

1.0 Design Description

This reference design implements a High IF Receiver circuit

that utilizes an LMH6515 DVGA and ADC14V155 Analog to

Digital Converter (ADC). The design illustrates variable gain

IF amplification and digitization in wireless infrastructure sys-

tems and frequency domain analyzers. This flexible subsys-

tem provides excellent sensitivity for input signal frequencies

up to 240 MHz. It achieves a small-signal SNR of 72 dBFS

and a SFDR greater than 90 dBFS with a 169 MHz input fre-

quency. Large signal performance yields a SNR of 68.3 dBFS

and SFDR of 77 dBFS at 169 MHz. In addition to the

LMH6515, the design includes National’s ADC14V155 14-bit,

155 MSPS ADC with dual data rate, parallel LVDS outputs.

The timing is provided by the LMK03001C low-jitter precision

clock conditioner with an integrated voltage-controlled oscil-

lator (VCO) that provides 190 femtosecond (fs) jitter over an

integration bandwidth of 100 Hz to 20 MHz; as well as several

energy-efficient power management ICs.
