MC145166 ? mc145167 motorola 6 pin descriptions input pins osc in /osc out reference oscillator input/output (pins 1,16) these pins form a reference oscillator when connected to an external parallelresonant crystal. for a 46/49 mhz cord- less 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 . mode mode select (pin 2) 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 pulldown device. sb standby input (pin 3) the standby pin is used to save power when not transmit- ting. 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 e 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 de- coding logic defaults to channel 10. the frequency assign- ments with reference to mode and d0 d3 are shown in table 1. these inputs have internal pulldown devices. f in1 , f in2 frequency inputs (pins 14, 9) f in1 and f in2 are inputs to the dividebyn 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 pp. clk, data clock, data (mc145167 e pins 5, 6) these pins provide the bcd input by using serial channel programming instead of parallel. logical high represents a 1. each lowtohigh transition of the clock shifts one bit of data into the onchip shift register. enb enable (mc145167 e pin 8) the enable pin controls the data transfer from the shift reg- ister to the 4bit latch. a positive pulse latches the data. output pins 5 k 5 khz tone signals (pin 4) the 5 khz tone signals are nchannel, opendrain out- puts derived from the reference oscillator. ld lock detect signal (pin 10) the lock detect signal is associated with the transmit loop. the lock output goes high to indicate an outoflock condi- tion. this is a pchannel opendrain output. pd1, pd2 phase detector outputs (pins 13, 11) these are threestate outputs of the transmit and receive phase detectors for use as loop error signals. phase detector gain is v dd /4 p volts per radian. frequency f v > f r or f v leading: output = negative pulses frequency f v < f r or f v lagging: output = positive pulses frequency f v = f r and phase coincidence: output = high impedance state power supply v ss negative power supply (pin 12) this pin is the negative supply potential and is usually ground. v dd 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 v ss .
