RD-179: High-IF Sub-

sampling Receiver

Subsystem

1.0 Design Description

The SP16160CH1RB demonstrates a high-IF sampling re-

ceiver subsystem that provides signal amplification, digitiza-

tion and clocking as used in wireless infrastructure systems.

The subsystem includes the ADC16DV160 analog-to-digital

converter (ADC), LMH6517 Digitally-controlled Variable-Gain

Amplifier (DVGA) and LMK04031B precision clock condition-

er.

In the signal path, the subsystem provides impedance-

matched, single-to-differential conversion through a 1:4 trans-

former and a 31.5 dB amplification gain range in 0.5 dB steps

through the DVGA. The anti-aliasing filter at the output of the

DVGA provides noise filtering and over 40 dB harmonic sup-

pression by selecting the 20 MHz signal band centered at 192

Hz. The signal is then sampled and quantized by the ADC into

16-bit words using a 153.6 MHz CMOS clock.

In the clock path, a LMK04031B clock conditioning circuit op-

erates with a 61.44 MHz reference oscillator and 76.8 Hz

VCXO to provide the 153.6 MHz CMOS sampling clock. The

clock output is also filtered and buffered to provide very low

broadband noise for less than 200 fs total jitter over the clock

input bandwidth of the ADC.

The measured system performance demonstrates a large

signal SNR of 71 dBFS and SFDR greater than 80 dBFS for

a -1 dBFS, 192 MHz input signal and a sampling frequency

of 153.6 MSPS. For signals less than -6 dBFS, the SNR is

greater than 72.7 dBFS and the SFDR is greater than 92

dBFS.

In a channel bandwidth of 200 kHz the subsystem achieves

a small signal channel SNR greater than 99 dBFS enabling

use in MC-GSM wireless communications receiver applica-

tions. In the presence of a -4 dBFS blocking signal that is 800

kHz from the channel center, the SP16160CH1RB achieves

a SNR of 94 dBFS and SFDR of 90 dBFS in the channel.

Evaluation of this reference board is simplified with the Wave-

Vision 5.1 Data Capture Board and WaveVision 5 software

which enables data capture and analysis, as well as complete

programmable configuration of the ADC16DV160 and

LMH6517 via a common SPI bus. The LMK04031B is easily

configured using a PIC Loader board that is included with the

reference kit.

The

SP16160CH1RB board, the PIC Loader board to program the

LMK04031B, and a WaveVision 5.0 software CD. Design

documents such as the schematic, BOM and Gerber files are

available on the web at www.national.com.
