1 / 2 page MC145168 •MC145169 MOTOROLA 1 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; Consult Factory NOT RECOMMENDED FOR NEW DESIGNS; PRODUCT TO BE PHASED OUT. Closest equivalent is MC145162.
