MK9173-01CS08T

Overview

The MK9173-01CS08T is a video genlock PLL clock synthesizer manufactured by Renesas Electronics Corporation (formerly IDT). It provides analog PLL circuit blocks, including a phase detector, charge pump, loop filter, and VCO, to implement frequency multiplication using an external divider. Designed for negative-going clock edge inputs, it supports reference frequencies from 12 kHz to 1 MHz. The -01 variant generates output clocks ranging from 1.25 MHz to 75 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: phase detector, charge pump, loop filter, and VCO
• Supports large frequency multiplication ratios via external feedback divider
• Reference clock range of 12 kHz to 1 MHz for full output clock range
• Output clock range of 1.25 to 75 MHz (-01) or 0.625 to 37.5 MHz (-15)
• On-chip loop filter eliminates external components

Applications

• Video genlock circuits for synchronizing free-running video sources
• Generating stable video dot clocks from H-SYNC signals
• Frequency multiplier implementations using low-frequency input clocks

Procurement Notes

Verify the ordering suffix 'T' indicates tape and reel packaging as specified in the datasheet. Confirm the '-01' designation corresponds to the 1.25–75 MHz output range. Ensure compatibility with the 8-pin SOIC footprint. Check for RoHS compliance if required, noting that 'LF' suffixes denote lead-free configurations.

Selection Notes

Select the MK9173-01 variant for output frequencies up to 75 MHz; choose MK9173-15 for outputs up to 37.5 MHz. Ensure the application requires negative-edge triggered inputs. Verify that an external digital divider is available for the feedback path. Confirm the system operates within the 0°C to +70°C temperature range and uses a 5V supply.

Part Context

The MK9173-01/-15 is pin and function compatible with the AV9173-01/15. The device shares the same die as the AV9173-15CS08. It is intended for normal commercial applications and is not recommended for extended temperature ranges or high reliability requirements without additional processing.

Replacement Considerations

The MK9173-01/-15 is directly compatible with the AV9173-01/15. For new video genlock applications, consider the ICS673-01, ICS1522, or ICS1523 as alternative solutions.
