GND
These pins must be connected to
a high quality RF/DC ground.
3INP
Positive T/H RF input (input bias -T). Has on-chip DC
50Ω termination, nominal max single-ended input level
= ±0.25V (-2 dBm) for specified performance. Input AC
coupling time constant ~ 10 ns, +10 dBm max.
4INN
Negative T/H RF input (input bias -T). Has on-chip DC
50Ω termination, nominal max single-ended input level
= ±0.25V (-2 dBm) for specified performance. Input AC
coupling time constant ~ 10 ns, +10 dBm max.
6VccSH
T/H core supply. Requires nominal current of 61.5 mA
at 5V. A 10 nF X7R dielectric chip capacitor close to the
device is recommended.
7
N/C
This pin must be left floating.
8VccCLK
Clock buffer power. Requires 19.8 mA
nominal current at 5V.
9, 10
CLKN, CLKP
Negative CLK RF input, Positive CLK RF input (CLK input
bias -T). Has on-chip 50Ω termination, +10 dBm max. AC
coupling time constant ~17 ns.
11, 12
CLKDCP, CLKDCN
Positive CLKDC input and Negative CLKDC input (CLK
input bias-T). A 10 n F X7R dielectric chip capacitor or
equivalent should be used here. Internal bias -T isolation
resistor = 1kΩ. May be floated for T/H operation. If biased
use common mode voltage of 2.5 V. Apply differential
voltage of (CLKDCP – CLKDCN ) > 20 mV to force device
in steady state track mode (in the absence of a clock). A
40 mV differential voltage can be continuously applied that
allows the device to be biased in track mode whenever the
clock is turned off.
