SPI/MICROWIRE-Compatible
UART in QSOP-16
This oscillator supports parallel-resonant mode crystals
and ceramic resonators, or can be driven from an
external clock source. Internally, the oscillator consists
of an inverting amplifier with its input, X1, tied to its out-
put, X2, by a bias network that self-biases the inverter
at approximately VCC / 2. The external feedback circuit,
usually a crystal, from X2 to X1 provides 180掳 of phase
shift, causing the circuit to oscillate. As shown in the
standard application circuit, the crystal or resonator is
connected between X1 and X2, with the load capaci-
tance for the crystal being the series combination of C1
and C2. For example, a 1.8432MHz crystal with a spec-
ified load capacitance of 11pF would use capacitors of
22pF on either side of the crystal to ground. Series-res-
onant mode crystals have a slight frequency error, typi-
cally oscillating 0.03% higher than specified series-
resonant frequency, when operated in parallel mode.
It is very important to keep crystal, resonator, and
load-capacitor leads and traces as short and direct as
possible. The X1 and X2 trace lengths and ground
tracks should be tight, with no other intervening traces.
This helps minimize parasitic capacitance and noise
pickup in the oscillator, and reduces EMI. Minimize
capacitive loading on X2 to minimize supply current.
