Advance Information
Dual PLLs for 46/49 MHz
Cordless Telephones
CMOS
These devices are dual phase–locked loop frequency synthesizers intended
for use primarily in 46/49 MHz cordless phones with up to 15 channels. These
parts contain two mask–programmable counter ROMs for receive and transmit
loops with two independent phase detect circuits. A common reference
oscillator and reference divider are shared by the receive and transmit circuits.
Other features include a lock detect circuit for the transmit loop, illegal code
default, a buffered oscillator output for mixing purposes in the system, and a
5.0 kHz tone output.
Maximum Operating Frequency: 60 MHz @ Vin = 200 mV p–p
Operating Temperature Range: – 40 to + 75°C
Operating Voltage Range: 2.5 to 5.5 V
On–Chip Oscillator Circuit Supports External Crystal
Operating Power Consumption: 3.0 mA @ 3.0 V
Lock Detect Signal
Standby Mode for Power Savings: 1.5 mA @ 3.0 V
Two Versions:
MC145168 — Up to 15–Channel ROM with 4–Bit Binary Code Input for
Channel Pair Selection
MC145169 — Up to 15–Channel ROM with Serial Interface for Channel
Pair Selection
Custom 20–Channel ROM Versions of the MC145169 are Possible;
