Description
Acknowledge
Address selection bits, see
programmable divider bits:
N = 2
charge pump current bit:
bit = 0: charge pump current = 50 µA or 125 µA
bit = 1: charge pump current = 250 µA (default) or 650 µA, see
test bits,
reference divider bits, see
tuning amplifier control bit:
bit = 0: enable V
disable XTAL buffer control bit:
bit = 0: enable XTAL buffer (default); bit = 1: disable XTAL buffer
PNP ports control bits:
bit = 0: Port is inactive, high impedance state (default)
bit = 1: Port is active, V
NPN port control bit:
bit = 0: Port is inactive, high impedance state (default)
bit = 1: Port is active, V
RF AGC time constant bit:
bit = 0: I
bit = 1: I
RF AGC take-over point bits, see
Loop through:
bit = 0: disable loop through (default); bit = 1: enable loop through
Power-on reset flag, bit = 1 at power-on
PLL lock flag, bit = 1: loop is locked
Narrow Band detector flag, bit =1 when SAWOUT level is above RF AGC
take-over point
internal AGC flag, bit = 1 when internal AGC is active (level below 3V)
