Order this document by MC145166/D SEMICONDUCTOR TECHNICAL DATA CMOS These devices are dual phase–locked loop (PLL) frequency synthesizers in– tended for use primarily in 46/49 MHz cordless phones with up to 10 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. Frequency selection is accomplished via a 4–bit parallel input for the MC145166. The MC145167 utilizes a serial interface. Other features include a lock detect circuit for the transmit loop, illegal code default, and a 5 kHz tone output. • • • • • • • • • Synthesizes Up to Ten Channel Pairs 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 Lock Detect Signal Operating Power Consumption: 3.0 mA @ 3.0 V Standby Mode for Power Savings: 1.5 mA @ 3.0 V Also See MC145162 P SUFFIX PLASTIC DIP CASE 648 16 1 DW SUFFIX SOG PACKAGE CASE 751G 16 1 ORDERING INFORMATION MC145166P Plastic DIP MC145166DW SOG Package MC145167P Plastic DIP MC145167DW SOG Package PIN ASSIGNMENTS MC145166P MC145166DW OSCout 1 16 OSCin MODE 2 15 VDD SB 3 14 fin1 5k 4 13 PD1 D0 5 12 VSS D1 6 11 PD2 D2 7 10 LD D3 8 9 fin2 MC145167P MC145167DW OSCout 1 16 OSCin MODE 2 15 VDD SB 3 14 fin1 5k 4 13 PD1 DATA 5 12 VSS CLK 6 11 PD2 NC 7 10 LD ENB 8 9 fin2 NC = NO CONNECTION REV 2 1/98 TN98011400 Motorola, Inc. 1998 MOTOROLA MC145166•MC145167 1 BLOCK DIAGRAM fv = 5 kHz PHASE DET 1 13–BIT DIVIDE–BY–N RECEIVE COUNTER fin1 PD1 fr 13 VDD RECEIVE ROM LOCK DET TRANSMIT ROM SB LD * 14 14–BIT DIVIDE–BY–N TRANSMIT COUNTER fin2 PHASE DET 2 fv PD2 OSCin MODE * REFERENCE COUNTER DIVIDE–BY–2048 OSCout 5 kHz fr * D0 D1 MC145166 ONLY * DECODE LOGIC D2 * D3 5k 4–BIT LATCH ENB VSS CLK 4–BIT S/R * On–chip pull–down.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high–impedance circuit. For proper operation, Vin and Vout should be constrained to the range VSS ≤ (Vin or Vout) ≤ VDD. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must be left open. * Maximum Ratings are those values beyond which damage to the device may occur. Functional operation should be restricted to the limits in the Electrical Characteristics tables or Pin Descriptions section.

MOTOROLA MC145166•MC145167 5 PIN DESCRIPTIONS INPUT PINS OSCin/OSCout Reference Oscillator Input/Output (Pins 1,16) These pins form a reference oscillator when connected to an external parallel–resonant crystal. For a 46/49 MHz cordless phone application, a 10.24 MHz crystal is needed. OSC in may also serve as input for an externally generated reference signal. This signal is typically ac coupled to OSC in, but for larger amplitude signals (standard CMOS logic levels) dc coupling may also be used. In the external reference mode, no connection is required for OSC out . CLK, DATA Clock, Data (MC145167 — Pins 5, 6) These pins provide the BCD input by using serial channel programming instead of parallel. Logical high represents a 1. Each low–to–high transition of the clock shifts one bit of data into the on–chip shift register. ENB Enable (MC145167 — Pin 8) The enable pin controls the data transfer from the shift register to the 4–bit latch. A positive pulse latches the data. OUTPUT PINS MODE Mode Select (Pin 2) 5k 5 kHz Tone Signals (Pin 4) Mode is for determining whether the part is to be used in the base or handset of a cordless phone. Internally, this pin is used in the decoding logic for selecting the ROM address. When high, the device is set in the base mode, and when low, it is set in the handset mode. This input has an internal pull–down device. The 5 kHz tone signals are N–channel, open–drain outputs derived from the reference oscillator. SB Standby Input (Pin 3) The standby pin is used to save power when not transmitting. When high, both the transmit and receive loops are in operation. When low, the transmit loop is disabled, thereby reducing power consumption. This input has an internal pull– down device. D0 – D3 Data Inputs (MC145166 — Pins 5 – 8) These inputs provide the BCD code for selecting the one of ten channels to be locked in both the transmit and receive loop. When address data other than 1 – 10 are input, the decoding logic defaults to channel 10. The frequency assignments with reference to Mode and D0 – D3 are shown in Table 1. These inputs have internal pull–down devices. fin1, fin2 Frequency Inputs (Pins 14, 9) fin1 and fin2 are inputs to the divide–by–N receive and transmit counters, respectively. These signals are typically derived from the loop VCO and are ac coupled. For larger amplitude signals (standard CMOS logic levels), dc coupling may be used. The minimum input level is 200 mV p–p. MC145166•MC145167 6 LD Lock Detect Signal (Pin 10) The lock detect signal is associated with the transmit loop. The lock output goes high to indicate an out–of–lock condition. This is a P–channel open–drain output. PD1, PD2 Phase Detector Outputs (Pins 13, 11) These are three–state outputs of the transmit and receive phase detectors for use as loop error signals. Phase detector gain is VDD/4 π volts per radian. Frequency fv > fr or fv leading: Output = Negative pulses Frequency fv < fr or fv lagging: Output = Positive pulses Frequency fv = fr and phase coincidence: Output = High– impedance state POWER SUPPLY VSS Negative Power Supply (Pin 12) This pin is the negative supply potential and is usually ground. VDD Positive Power Supply (Pin 15) This pin is the positive supply potential and may range from + 2.5 to + 5.5 V with respect to VSS. MOTOROLA Table 1.
