ML145162 Datasheet | LANSDALE Semiconductor

features fully programmable receive, transmit, reference, and auxiliary reference counters accessed through an MCU serial interface. This feature allows this device to operate in any CT- 1 cordless phone application. The device consists of two independent phase detectors for transmit and receive loops. A mon reference oscillator, driving two independent reference frequency counters, provides independent reference frequencies for transmit and receive loops. The auxiliary reference counter allows the user to select an additional reference frequency for receive and transmit loops if required. - - - - - - - - - - - - - Operating Voltage Range: 2.5 to 5.5 V Operating Temperature Range: TA = - 40 to +75°C Operating Power Consumption: 3.0 m A @ 2.5 V Maximum Operating Frequency: 60 MHz @ 200 m V p- p, VDD = 2.5 V Three or Four Pins Used for Serial MCU Interface Built- In MCU Clock Output with Frequency of Reference Oscillator ÷3/÷4 Power Saving Mode Controlled by MCU Lock Detect Signal On- Chip Reference Oscillator Supports External Crystals to 16.0 MHz Reference Frequency Counter Division Range: 16 to 4095 Auxiliary Reference Frequency Counter Division Range: 16 to 16,383 Transmit Counter Division Range: 16 to 65,535 Receive Counter Division Range: 16 to 65,535 P DIP 16 = EP PLASTIC DIP CASE 648 16 1 SOG 16 = -5P SOG PACKAGE CASE 751B CROSS REFERENCE/ORDERING INFORMATION PACKAGE LANSDALE MOTOROLA P DIP 16 SOG 16 MC145162P MC145162D ML145162EP ML145162-5P Note: Lansdale lead free (Pb) product, as it bees available, will be identified by a part number prefix change from ML to MLE.
