5036 series 2.5V LV-PECL Output Oscillator ICs OVERVIEW The 5036 series are 2.5V operation, differential LV-PECL output oscillator ICs. They support 50MHz to 400MHz 3rd overtone oscillation and 50MHz to 600MHz fundamental oscillation. The devices are fabricated using a proprietary BiCMOS process, enabling a high-frequency oscillator circuit and differential LV-PECL output buffer to be incorporated on a single chip. The 5036 series can be used to construct high-frequency LVPECL output oscillators.

Oscillator equivalent circuit C0 cancel CXIN Rf XIN RPD CXOUT XOUT Oscillator block equivalent circuit The 5036G×/A×/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 5036E× 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 to OUT and OUTN pins (excluding measurement circuit 3). 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.

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 5036 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.
