Pin No. Function Name I/O Detail of Function
Reset (active low). When asserted, the chip is placed in the reset state and the peripheral pins are
config
u red as inp u ts. After deassertion of NRESET, the chip is clocked by XTALI and starts booting from the
port config u red by the FCLE, FALE pins.
D13 NRESET I
The NRESET signal m u st be asserted after power- u p.
K3 XTALI I Oscillator circ u it inp u t. Internal system clock will be derived from XTALI (internal clock m u ltiplier).
J3 XTALO O Oscillator circ u it o u tp u t.
C7 RREF I Reference c u rrent. Connect a 3.0 k-ohms ±1% resistor to GND.
B10 TEST1 I Reserved. Connect to VDD for normal operation.
A10 HIGHZ I Reserved. Connect to VDD for normal operation.

VCO[1:0] I
External oscillator inp u ts, typically coming from an external VCO. Together with the external loop-filter and
the internal clock dividers, each PDOUT/VCO pair can form a complete PLL.

PDOUT[1:0] O
Phase discriminator o u tp u ts. These signals are charge-p u mp type o u tp u ts.
K1 Each of them can be u sed to feed the loop-filter of a PLL str u ct u re.
