Description
FLoutRF
O
RF PLL Fastlock output. This pin connects a resistor in parallel to R2 of the
external loop filter. This pin can also function as a general purpose CMOS
TRI-STATE output.
Ground for the RF PLL digital circuits.
RF PLL charge pump output. The output is connected to the external loop filter,
which drives the input of the RF VCO.
Ground for the RF PLL analog circuits.
RF PLL prescaler input. Small signal input from the VCO.
RF PLL prescaler complementary input. For single ended operation, this pin
should be AC grounded through a 100 pF capacitor. The LMX243x can be
driven differentially when the AC coupled capacitor is omitted.
Power supply bias for the RF PLL analog circuits. Vcc may range from 2.25V to
2.75V. Bypass capacitors should be placed as close as possible to this pin and
be connected directly to the ground plane.
MICROWIRE Latch Enable input. High impedance CMOS input. When LE
transitions HIGH, DATA stored in the shift register is loaded into one of 6
internal control registers.
MICROWIRE Clock input. High impedance CMOS input. DATA is clocked into
the 24-bit shift register on the rising edge of CLK.
MICROWIRE Data input. High impedance CMOS input. Binary serial data. The
MSB of DATA is shifted in first. The two last bits are the control bits.
Power supply bias for the IF PLL analog and digital circuits, MICROWIRE, and
Ftest/LD circuits. Vcc may range from 2.25V to 2.75V. Bypass capacitors
should be placed as close as possible to this pin and be connected directly to
the ground plane
