CPPE7-A7BR-122.50

Oscillators Overview

The CPPE7-A7BR-122.50 is a field-programmable blank oscillator from Cardinal Components, designed for rapid customization. It delivers an LVPECL output signal at a nominal frequency of 122.5 MHz. The device operates within a supply voltage range of 3.3 V and maintains a frequency stability of ±25 ppm. Physically, it utilizes a compact surface-mount ceramic package measuring 7.0 mm x 5.0 mm with a maximum seated height of 2.00 mm. It supports operation across a temperature range of -40 °C to +85 °C and is RoHS compliant.

Oscillators Feature Summary

• Field programmable blank oscillator allowing on-the-fly frequency customization using PG-3000 instruments
• LVPECL output interface providing high-speed differential signaling capabilities
• Compact 5x7mm ceramic surface-mount package suitable for space-constrained designs

Oscillators Applications

• High-speed digital communication systems requiring precise clocking
• Data acquisition equipment needing customizable frequency standards
• Telecommunications infrastructure utilizing LVPECL interfaces

Oscillators Procurement Notes

Verify the specific programming instrument compatibility, such as the PG-3000, required to configure the blank oscillator to the desired frequency. Confirm that the LVPECL output level matches the receiving component's input requirements. Ensure the operating temperature range meets the environmental conditions of the final assembly. Check for any specific handling precautions related to the ceramic surface-mount package during reflow soldering processes.

Oscillators Selection Notes

Select this component when a custom LVPECL frequency near 122.5 MHz is required without maintaining large inventories of pre-programmed units. The field-programmable nature allows for flexibility in production runs or prototyping phases. Consider the ±25 ppm stability requirement against system jitter budgets. Evaluate the 3.3 V supply constraint against available power rails in the target design.

Oscillators Part Context

This part belongs to the CPPE series of field-programmable blank oscillators from Cardinal Components. These devices are designed to be programmed by end-users or integrators using specialized hardware tools. The series offers various output types and packages, with the CPPE variant specifically supporting LVPECL outputs in a standard 5x7mm footprint.

Oscillators Replacement Considerations

Direct replacements must match the LVPECL output type, 122.5 MHz frequency, and 5x7mm SMD package. Verify that alternative suppliers offer compatible field-programmable blank units if inventory management strategies require switching vendors. Ensure pinout compatibility and electrical specifications align precisely.
