MK9173-15CS08LF

Overview

The MK9173-15CS08LF is a video genlock PLL clock synthesizer manufactured by Renesas Electronics Corporation (formerly IDT). It provides analog PLL circuit blocks for frequency multiplication using an external divider in the feedback path. The device integrates a phase detector, charge pump, loop filter, and voltage-controlled oscillator (VCO). Designed for single 5 V power supply operation with low power CMOS technology, it operates within a temperature range of 0 to +70 °C. The -15 variant generates output frequencies ranging from 0.625 MHz to 37.5 MHz, which are exactly half of the MK9173-01 frequencies. It is housed in an 8-pin SOIC package.

Feature Summary

• Integrates phase detector, charge pump, on-chip loop filter, and VCO for analog PLL implementation
• Supports reference clock input range of 12 kHz to 1 MHz
• Output clock range of 0.625 MHz to 37.5 MHz (-15 variant)
• Pin and function compatible with AV9173-01/15

Applications

• Video genlock circuits for synchronizing free-running video sources
• Generating high-frequency dot clocks from low-frequency H-SYNC references
• Frequency multiplier implementations requiring large division ratios

Procurement Notes

Verify that the ordering suffix 'LF' indicates a Pb-Free configuration that is RoHS compliant. Confirm the specific die compatibility if substituting with AV9173-15CS08, as both part numbers utilize the same silicon. Ensure the application environment remains within the recommended operating temperature range of 0 to +70 °C.

Selection Notes

Select the MK9173-15 variant when output frequencies between 0.625 MHz and 37.5 MHz are required. The MK9173-01 should be chosen for outputs up to 75 MHz. Both inputs, IN and FBIN, respond only to negative-going clock edges. An external digital divider, such as the ICS674-01, must be used in the feedback path to establish the multiplication ratio.

Part Context

This component belongs to the MK9173-01/-15 series of video genlock PLLs. It serves as a direct replacement or equivalent for the AV9173-15CS08, sharing the same die. The device is intended for normal commercial applications and is not recommended for extended temperature ranges or critical medical instruments without additional processing.

Replacement Considerations

The MK9173-15CS08 is pin and function compatible with the AV9173-15CS08. For new video genlock designs, consider the ICS673-01, ICS1522, or ICS1523.
