MK3771-17RLFTR

Overview

The MK3771-17RLFTR is a clock and frequency synthesizer integrated circuit manufactured by Renesas Electronics Corporation. It operates with a core voltage of 3.3V and accepts a crystal input frequency of 13.5 MHz. The device generates HDTV frequencies including 74.25 MHz and 74.175824 MHz. It features an on-chip patented Voltage Controlled Crystal Oscillator (VCXO) with a minimum pull range of 200 ppm. The component is housed in a 28-pin SSOP package, which measures 0.154 inches or 3.90 mm in width.

Feature Summary

• Integrates a patented VCXO for precise frequency control
• Designed as a low jitter clock source for digital video applications
• Supports specific high-definition television output frequencies

Applications

• Set-top boxes
• HDTV receivers

Procurement Notes

Verify the exact ordering suffix to ensure compatibility with the required tape and reel packaging format. Confirm that the 28-SSOP package dimensions align with the target PCB footprint. Check for lead-free compliance status if environmental regulations apply to the assembly process. Ensure the 3.3V supply voltage matches the system design requirements before procurement.

Selection Notes

Select this component when a dedicated clock synthesizer with integrated VCXO functionality is required for HDTV signal processing. The fixed input frequency of 13.5 MHz limits flexibility compared to programmable synthesizers. Consider the 28-pin SSOP package size constraints during layout planning. This part is suitable for applications prioritizing low jitter performance over wide-range frequency agility.
