CDC857-3DGGG4 Overview
In order to package it as a clock IC, the Tube package is used. A Clock PLL is included with the 48-TFSOP (0.240, 6.10mm Width) package. Frequency generator can maintain a maximum temperature of NOT SPECIFIED under reflowing conditions. As a result of this, we can find 48 terminations. Clock generator ics require a voltage of 2.5V. As the Clock PLL's input, LVTTL, SSTL-2 is designed to be used in order to generate the clock signal. It is possible to access the full performance of the electrical part by implementing 1 circuits. Surface Mount-slots make it easy to mount this electronic component on panels. It would take a maximum supply voltage of 2.7V to operate this time clock generator. Safety considerations dictate that the supply voltage for this frequency synthesizer should be greater than 2.3V. Clock generator ic works with 3V~3.6V. By calculating the test statistics, 0°C~85°C is the appropriate ambient temperature. SSTL-2 logic levels are supported by this RF synthesizer. PLL Clock Driver is the type of electrical part that this component is classified as. It is a 48-bit IC that is designed for microprocessors specifically. Related electrical parts can be found for the base part number CDC857. The clock PLL has 48 pins that are available. In terms of the supply voltage, PLL clock can handle 3.3V volts. This frequency synthesizer features ALSO REQUIRES 3.3V PLL VOLTAGE to produce better clock signals. At frequencies of 167MHz, RF synthesizer achieves high efficiency.
