Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Shenzhen Mingjiada Electronics Co., Ltd. acquires TI Automotive IC CDCE6214LTWRGERQ1 supports PCIe® Generation 1 to Generation 5, has a low-level effective output enable terminal ultra-low power clock generator, only recycling formal channel sources, such as agents, traders, terminal factories and so on.

Description

The CDCE6214LTWRGERQ1 is a 4-channel, ultra-low-power, mid-level jitter clock generator for automotive applications that generates five independent clock outputs selectable between various driver modes. The input source can be a single-ended or differential input clock source, or a crystal. The CDCE6214Q1TM features a fractional N PLL that synthesises an uncorrelated base frequency at any input frequency.

Features

Complies with AEC-Q100 for automotive applications

Temperature class 2: -40°C to +105°C

Functional Safety

Documentation available for functional safety system designs

RMS jitter and spurious (12kHz - 20MHz, F out > 100MHz) allows the high performance, low power fractional N PLL to be configured as follows:

Integer mode:

Differential output: 350fs typical, 600fs maximum

LVCMOS output: 1.05ps typical, 1.5ps maximum

Fractional mode:

Differential output: 1.7ps typical, 2.1ps max.

LVCMOS output: 2.0ps typical, 4.0ps maximum

Supports PCIe Gen1/2/3/4 with SSC and Gen 1/2/3/4/5 without SSC

Internal VCO: 2.335 GHz to 2.625 GHz

Typical power consumption: 65mA for 4 output channels, 23mA for single output channel.

Universal clock input, two reference inputs for redundant support

Differential AC coupling or LVCMOS: 10MHz to 200MHz

Crystal: 10MHz to 50MHz

Flexible output clock distribution

4-channel frequency divider: up to five unique output frequencies ranging from 24kHz to 328.125MHz

OUT0 - OUT4 pins have LVDS-like, LP-HCSL or LVCMOS outputs

Burr-free output divider switching and output channel synchronisation

Separate output enables via active-low GPIOs and registers

Frequency margin options
