Introduction to CXD2463R

The CXD2463R is a specialist IC that generates synchronization signals for timing control and back-end signal processing in a CCD (Charge-Coupled Device) camera system. Because of their high light sensitivity and image clarity, CCDs are frequently utilized in surveillance cameras, doorbell cameras, and other imaging applications. The CXD2463R keeps the CCD camera system running smoothly and efficiently.

Features of CXD2463R

● Built-in Sync Signal Generation

One of the CXD2463R’s unique features is its ability to create synchronization signals internally. These sync signals are critical for timing control, which ensures that the CCD image sensor records images at the correct time and without distortion or artifacts.

● Electronic Iris (Electronic Shutter) Function

The CXD2463R has an integrated electronic iris feature. This electronic shutter technology provides precise control over the camera’s exposure to light, allowing it to easily adapt to changing lighting situations.

● Low-Speed Limiter for Electronic Iris

A low-speed limiter is available in addition to the electronic iris function on the CXD2463R. This capability is especially beneficial in settings requiring regulated exposure adjustments, such as transitioning from bright outside surroundings to dimly lit interiors.

● External Synchronization

The CXD2463R provides versatility by supporting external synchronization methods such as Line-Lock and VReset+HPLL. This functionality ensures that the camera can be coordinated with external devices or systems.

● Automatic External Sync Discrimination

The CXD2463R includes automatic external sync discrimination to ease setup and operation. This means it can detect and adjust to external synchronization signals intelligently, avoiding the requirement for manual configuration.

● Window Pulse Output for Backlight Compensation

The CXD2463R has a window pulse output that can be used for backlight correction to improve image quality. This function assists the camera in capturing clean and balanced photographs even in low-light situations.

● Built-in V Driver

The CXD2463R has an integrated V driver, which is critical for precise control of vertical scanning in a CCD camera system. This improves the camera’s overall image quality and dependability.

Understanding the Operating Conditions of CXD2463R

The CXD2463R is a versatile integrated circuit that is utilized in a variety of applications; it is critical to run it within the parameters given to ensure optimal performance and dependability. This tutorial will look into the CXD2463R’s suggested working parameters, shining light on voltage needs and temperature issues.

Voltage Requirements

• Supply Voltage 1 (VDD, AVDD): The CXD2463R requires a supply voltage between 4.75V and 5.25V. This voltage level is required for the device to power on and perform its tasks. To ensure appropriate operation, offer a stable and within-range supply voltage.

• Supply Voltage 4 (VL): VL is a -9.0V to -8.0V negative supply voltage. It has a specific function in the CXD2463R’s operation. To keep VL within the defined limits, accurate voltage management is required.
• Supply Voltage 5 (VM): VM is denoted by 0V and represents a reference voltage point. It is critical for proper operation to keep this reference voltage at 0V.

Temperature Range

The operating temperature range of the CXD2463R is another critical consideration:

• Operating Temperature (Topr):The CXD2463R can work consistently in temperatures ranging from -20°C to +75°C. This range covers a wide range of environmental conditions, making the IC appropriate for use in a variety of climates and locations.

Base Oscillation

The CXD2463R operates on base oscillation frequencies. The following frequencies are specified:

• 1212fH (EIA):0699MHz (CCIR: 18.9375MHz)
• 1820fH (EIA):6364MHz
• 1816fH (CCIR):375MHz

These base oscillation frequencies are fundamental to the CXD2463R’s functionality and timing control.
