The CDCE6214 is a four-channel, ultra-low power, medium grade jitter, clock generator that can generate five independent clock outputs selectable between various modes of drivers. The input source can be a single-ended or differential input clock source, or a crystal. The CDCE6214 features a frac-N PLL to synthesize unrelated base frequency from any input frequency. The CDCE6214 can be configured through the I2C interface. In the absence of the serial interface, the GPIO pins can be used in Pin Mode to configure the product into distinctive configurations.
The CDCE6214 can be configured through the I2C interface in fall-back mode only. In the absence of the serial interface, the GPIO pins can be used in pin mode to configure the product into distinctive configurations.
On-chip EEPROM can be used to change the configuration, which is pre-selectable through the pins. The device provides frequency margining options with glitch-free operation to support system design verification tests (DVT) and Ethernet Audio-Video Bridging (eAVB). Fine frequency margining is available on any output channel by steering the fractional feedback divider in DCO mode.
Internal power conditioning provides excellent power supply ripple rejection (PSRR), reducing the cost and complexity of the power delivery network. The analog and digital core blocks operate from either a 1.8V, 2.5V, or 3.3V ±5% supply, and output blocks operate from a 1.8V, 2.5V, or 3.3V ±5% supply.
The CDCE6214 enables high-performance clock trees from a single reference at ultra-low power with a small footprint. The factory- and user-programmable EEPROM features make the CDCE6214 an easy-to-use, instant on clocking device with a low power consumption.
