The TMC57750PM is a highly specified, two-phase clock generator integrated with a programmable clock multiplier and voltage regulator (PMCVR), precision clock-divider, and a dual system oscillator. This device is targeted for the clock and timing application specific and offers enhanced features for performance. The features incorporated in this device enables applications such as audio mixing, setting different frequencies for single or dual channel systems, low voltage operating and flexible interconnect opportunities, allowing it to be used effectively in many common system level applications.

The TMC57750PM offer a wide range of frequency and voltage scalability. It offers programmable clock multipliers and divided ratios that are tightly regulated down to 0.5V with the help of a PMCVR. Its low-voltage operating range removes or eliminates the need for any external voltage regulator that can often be expensive. It contains four integrated programmable clock dividers which allow device to divide existing system clock rates as per user needs.

The highly programmable and efficient clock synthesis circuitry of the device makes it suitable for a range of applications including audio mixing, processor control, and rapid frequency scaling. The enhanced clock support provided by the device make it an ideal choice for many system level timing applications requiring accurate clock-divider ratios and flexible clock-generation.

The TMC57750PM comes with two internal system oscillators, allowing the user to configure them to different frequency rates. The device produces a full frequency output of up to 700MHz with a wide range of clocks available from internal, external, and programmable clock sources. The system oscillator is used as the basis for programming the clock multipliers and dividers for the generation of desired output frequencies.

The TMC57750PM offers a flexible architecture to ensure maximum design flexibility. It provides users with the flexibility to easily interface with several clock sources through serial or parallel interfaces. The device also contains several peripheral functions such as an internal high speed mode, optional external resets, and voltage monitoring. These functions allows the user to control the device and ensure robust design behavior.

The device also employs a protected programming interface. TMC57750PM’s programmable clock can be configured via either a serial or parallel interface. It contains a non-volatile memory that stores the settings and associated data, allowing it to retain the settings across power cycles. It also incorporates an enable/disable pin that allows the user to enable or disable the device from outside.

In summary, the TMC57750PM is a highly specified, two-phase clock generator integrated with a programmable clock multiplier and voltage regulator (PMCVR), precision clock-divider, and a dual system oscillator. It is an ideal choice for many system level timing applications requiring accurate clock-divider ratios and flexible clock-generation. The device combines highly programmable and efficient clock synthesis circuitry, allowing users to easily interface with several clock sources, program various clock multipliers, and quickly set different frequencies for single or dual channel systems.
