SEIKO NPC CORPORATION —3 OSCILLATOR CIRCUIT CONSTANT The 5037 series oscillator setting varies with device version to optimize characteristics over the recommended operating frequency range. 5037A1, 5037B , 5037C , 5037D , 5037E , 5037D1T The 5037A1/B /D1T versions are suitable for use of crystal unit with large C0 value (approximately 2.0pF (5037A1/B ×)/ 2.5pF (5037D1T ). The 5037E version is suitable for use of crystal unit with C0 value of approximately 2pF. Oscillator equivalent circuit Version Recommended crystal unit/ resonator Built-in capacitance [pF] *1. The oscillator internal capacitance values includes parasitic capacitance. Recommended oscillation frequency range [MHz] *2. The recommended oscillation frequency is a yardstick value derived from the crystal used for NPC characteristics authentication. However, the oscillator frequency band is not guaranteed.

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 oscill ator 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.

SEIKO NPC CORPORATION —9 MEASUREMENT CIRCUITS I Note: Bypass capacitors specified in each measurement circuit below should be connected between VCC and GND, and VCC2 and GND. Load resistance speci fied 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. Measurement Circuit 1 Measurement Circuit 2 Measurement Circuit 3 C1: 0.01µF , R1: 49.9Ω R1: 49.9Ω Note 1. The recommended differential probe used for measurement should have 5GHz analog bandwidth, ≥ 50kΩ impedance, and < 1pF capacitive load. Note 2. 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 —10 FUNCTIONAL DESCRIPTION Standby Function When OE goes LOW, the oscillator stops and the output pins (OUT, OUTN) become high impedance. 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. OE OUT, OUTN Oscillator HIGH (or open) Either f O or fO/2 Normal operation LOW High impedance Stopped
