DC1705C-C Overview

board demo ltc6946-3

DEMO MANUAL DC1705C
LTC6946
Ultralow Noise and Spurious Integer-N
Frequency Synthesizer with Integrated VCO
DESCRIPTION
DC1705C features the
LTC
®
6946,
an ultralow noise and
spurious integer-N frequency synthesizer with integrated
VCO. The VCO uses no external components and is inter-
nally calibrated without external system support.
There are four options of the DC1705C, one for each ver-
sion of the LTC6946. Table 1 summarizes the available
DC1705C options.
Each DC1705C provides 50Ω SMA connectors for the
reference frequency input, f
REF
(REF+ IN), the reference
output buffer (REF OUT), and the differential RF output
(RF
+
and RF
). A DC590 USB serial controller board is
used for SPI communication with the LTC6946, controlled
by the supplied PLLWizard™ software.
