Oscillator equivalent circuit C0 cancel CXIN Rf XIN RPD CXOUT XOUT Oscillator block equivalent circuit The 5037A1/B×/C×/D×(T)/E× oscillator circuit has a C0 cancel circuit built-in to improve the oscillator margin. If power is applied when there is an open circuit between XIN and XOUT, self oscillation may occur, which is not abnormal. Users should confirm that the oscillator operates normally when a crystal unit is connected. The XOUT pin of 5037E× version emphasizes high frequency characteristics. Accordingly, its electrostatic withstand voltage is significantly lower than that of the other pins. ESD breakdown prevention handling precautions are strongly recommended.

Load resistance specified in each measurement circuit below should be connected between OUT and OUTN pins (excluding measurement circuit 2). Circuit wiring of bypass capacitors and load resistance should be connected as short as possible. If the circuit wiring is long, the required characteristics may not be realized. Also, if the values of bypass capacitors and load resistance differ from the description in this document or are not connected, the required characteristics may not be realized.

If common-mode noise becomes a problem, a DC decoupling capacitor (approximately 1000pF) and terminating resistor matching the common-mode signal should be connected to the output center tap. SEIKO NPC CORPORATION —9 5037 series FUNCTIONAL DESCRIPTION Standby Function When OE goes LOW, the oscillator stops and the output pins (OUT, OUTN) become high impedance. OE OUT, OUTN Oscillator HIGH (or open) Either fO or fO/2 Normal operation LOW High impedance Stopped Power-saving Pull-up Resistor The OE pin pull-up resistance changes in response to the input level (HIGH or LOW). When OE is tied LOW (standby state), the pull-up resistance becomes large, reducing the current consumed by the resistance. When OE is open circuit, the pull-up resistance becomes small, decreasing the susceptibility to the effects of external noise. Oscillation Detector Function The 5037 series also feature an oscillation detector circuit. This circuit functions to disable the outputs until the oscillator circuit starts and oscillation becomes stable. This alleviates the danger of abnormal oscillator output at oscillator start-up when power is applied or when OE is switched.
