3 / 10 page SM5170AV NIPPON PRECISION CIRCUITS—3 PIN DESCRIPTION SPECIFICATIONS Absolute Maximum Ratings VSS = 0 V Recommended Operating Conditions VSS = 0 V Number Name I/O Supply Description 1 XIN I 1 V Reference frequency divider crystal oscillator connection pins. Alternatively, an external clock input can be connected to XIN. The clock is output on XOUT. Feedback resistor built-in for AC-coupled inputs. 2 XOUT O 1 V 3 VDD2 – 3 V Phase comparator, charge pump and booster signal 3 V supply 4 D B O 3 V Booster signal output for faster locking 5D O O 3 V Phase comparator output pin. Built-in charge pump and tristate output means that this output can be connected to a low-pass filter. The output polarity is preset for connection to a passive filter. 6 V S S – – Ground pin 7 F I N I 1 V FIN input frequency divider input pin. Feedback resistor built-in for AC-coupled inputs. 8 VDD1 – 1 V Reference frequency and FIN input frequency prescaler and counter 1 V supply 9 N C – – No connection 10 L D O 1 V Unlock signal output pin. (Unlocke d when LOW). The function of LD can be turned OFF using the LD input control bit (LD should be tied LOW when not used). 1 1 C L K I 3 V Control data clock input pin 1 2 D ATA I 3 V Control data input pin 1 3 L E I 3 V Control data latch enable signal input pin 1 4 O P R I 3 V P ow er-save control pin. Start when HIGH, standby mode when LOW . 1 5 N C – – No connection 1 6 TEST I 1 V Test pin. Pull-down resistor built-in. Leave open or connect to ground for normal operation.
