OV-7605-C8

Low Power Clock Oscillator 32.768 kHz

1. OVERVIEW

Oscillator with built-in “Tuning Fork” crystal oscillating at 32.768 kHz

Very tight frequency tolerance: ±20 ppm

Excellent oscillator stability: < 3 ppm/V

High shock and vibration resistance

Wide operating voltage range: 1.6 V to 5.5 V

Very low power consumption: typ. 450 nA

Standard operating temperature range TA: -40 to +85°C

CLKOUT enable/disable

Low aging rate

Ultra-miniature ceramic SMT package, RoHS-compliant and 100% lead-free: 2.0 x 1.2 x 0.85 mm

Available for Medical Implantable applications

Automotive qualification according to AEC-Q200 available

GENERAL DESCRIPTION1.1.

The OV-7605-C8 combines an advanced very low power CMOS oscillator circuitry together with a 32.768 kHz

“tuning-fork” crystal in an ultra-miniature ceramic package. No external components are required. The very low

power consumption over a wide supply voltage and temperature range is the key feature of this product.

The frequency output on CLKOUT pin can be enabled/disabled by the CLKOE pin. The CLKOUT frequency is

enabled when CLKOE pin is connected to VDD. When the CLKOE pin is tied to GND the frequency is disabled and

the CLKOUT pin is high impedance (Hi-Z).

The OV-7605-C8 is available for Medical Implantable applications.

APPLICATIONS1.2.

The OV-7605-C8 oscillator module combines very low power consumption with a ultra-small ceramic package:

Smallest oscillator module (embedded XTAL) in a ultra-small 2.0 x 1.2 x 0.85 mm lead-free ceramic

package

Price competitive

The unique size and the competitive pricing make this product perfectly suitable for many applications:

Communication: IoT / Wearables / Wireless Sensors and Tags / Handsets

Automotive: M2M / Navigation & Tracking Systems / Dashboard / Tachometers / Engine Controller

Car Audio & Entertainment Systems

Metering: E-Meter / Heating Counter / Smart Meters / PV Converter / Utility metering

Outdoor: ATM & POS systems / Surveillance & Safety systems / Ticketing Systems

Medical: Glucose Meter / Health Monitoring Systems / Implantable

Safety: Security & Camera Systems / Door Lock & Access Control

Consumer: Gambling Machines / TV & Set Top Boxes / White Goods

Automation: PLC / Data Logger / Home & Factory Automation / Industrial and Consumer Electronics

Description

CLKOUT

Clock Output; push-pull; controlled by CLKOE. If CLKOE is HIGH (VDD), the CLKOUT pin drives the

square wave of 32.768 kHz. When CLKOE is tied to Ground, the CLKOUT pin is high impedance

(Hi-Z).

GND

Ground.

CLKOE

Input to enable the CLKOUT pin. If CLKOE is HIGH, the CLKOUT pin is in output mode. When

CLKOE is tied to Ground, the CLKOUT pin is high impedance (Hi-Z).
