MK9173-15CS08T

Overview

The MK9173-15CS08T is a video genlock PLL clock synthesizer manufactured by Integrated Device Technology (IDT), now part of Renesas Electronics. It provides analog PLL circuit blocks for frequency multiplication using an external divider in the feedback path, enabling high-frequency output from low-frequency inputs. The device integrates a phase detector, charge pump, loop filter, and VCO. Designed for negative-going clock edge triggering, it supports reference frequencies from 12 kHz to 1 MHz. The -15 variant delivers an output clock range of 0.625 to 37.5 MHz. It operates on a single 5 V supply with low power CMOS technology and is housed in an 8-pin SOIC package.

Feature Summary

• Integrated analog PLL blocks including phase detector, charge pump, loop filter, and VCO
• Supports external feedback divider for large frequency multiplication ratios
• Reference clock input range of 12 kHz to 1 MHz
• Output clock range of 0.625 to 37.5 MHz for the -15 variant
• Pin and function compatible with AV9173-01/15

Applications

• Video genlock circuits for synchronizing free-running video sources
• Generating video dot clocks from horizontal synchronization signals
• Frequency synthesis for telecom and jitter attenuation applications

Procurement Notes

Verify that the ordering suffix 'T' indicates tape and reel packaging as specified in the IDT datasheet. Confirm the '-15' designation corresponds to the 0.625 to 37.5 MHz output range. Ensure compatibility with existing designs referencing the AV9173-15 series, noting they share the same die. Check for RoHS compliance if lead-free configuration is required, though standard parts are available.

Selection Notes

Select the MK9173-15 variant when the required output frequency does not exceed 37.5 MHz. Use the MK9173-01 variant for outputs up to 75 MHz. Ensure the reference input signal is stable with low jitter within the 12 kHz to 1 MHz range. Configure FS0 and OE pins appropriately; tie unused inputs to GND or VDD. Verify that the external divider ratio matches the desired pixel clock cycles per h-sync pulse.

Part Context

This component belongs to the MK9173 family of video genlock PLLs originally developed by Integrated Device Technology (IDT). Following IDT's acquisition by Renesas Electronics Corporation, these products are managed under Renesas. The MK9173-15 is functionally identical to the AV9173-15 but carries the MK prefix. It serves as a specialized solution for video synchronization tasks requiring precise dot clock generation.

Replacement Considerations

The MK9173-15CS08T is pin and function compatible with the AV9173-15CS08. Both parts use the same die and can be substituted directly in existing designs. For new applications, consider modern alternatives such as the ICS673-01, ICS1522, or ICS1523.
