CDCE6214TWRGERQ1

The CDCE6214-Q1 from Texas Instruments is an ultra-low power clock generator qualified for automotive applications (Temperature Grade 2: -40°C to 105°C). This device features one PLL, two inputs, and four differential outputs, with internal EEPROM.

It supports PCIe Gen1 through Gen5 with Spread Spectrum Clocking (SSC) and Gen1 through Gen6 without SSC. The device offers configurable high performance, low-power operation with low jitter. Integer mode differential outputs exhibit typical RMS jitter of 350fs and maximum of 600fs, while LVCMOS outputs have typical jitter of 1.05ps and maximum of 1.5ps. Fractional mode offers typical differential output jitter of 1.7ps and maximum of 2.1ps, with LVCMOS outputs at typical 2.0ps and maximum 4.0ps.

Flexible output clock distribution allows for up to five unique output frequencies ranging from 24kHz to 328.125MHz. Outputs can be configured as LVDS-like, LP-HCSL, or LVCMOS. The universal clock input accepts differential AC-coupled or LVCMOS signals from 10MHz to 200MHz, or a crystal from 10MHz to 50MHz. Power consumption is typically 65mA for a 4-output channel and 23mA for a 1-output channel.

The CDCE6214TWRGERQ1 is available in a 24-VQFN (4x4) package and is surface-mountable. It is designed for applications requiring precise clock generation and distribution in automotive environments.
