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×/C×/D×/D1T versions are suitable for use of crystal unit with large C0 value (approximately
C0 ≥ 2.0pF (5037A1/B×/C×/D×)/ C0 ≥ 2.5pF (5037D1T)). The 5037E× version is suitable for use of crystal
unit with C0 value of approximately 2pF.

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.

MEASUREMENT CIRCUITS
■
Note: Bypass capacitors specified in each measurement circuit below should be connected between VCC and
GND, and VCC2 and GND. 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.

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.

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.
