GS1531中文资料HD-LINX® II Multi-Rate Serializer with ClockCleaner™数据手册Semtech规格书

描述 Description

The GS1531 is a multi-standard serializer with an integrated cable driver. When used in conjunction with the GO1555/GO1525* Voltage Controlled Oscillator, a transmit solution can be realized for HD-SDI, SD-SDI and DVB-ASI applications.
The device features an internal PLL, which can be configured for loop bandwidth as narrow as 100kHz. Thus the GS1531 can tolerate in excess of 300ps jitter on the input PCLK and still provide output jitter well within SMPTE specification. Connect the output clocks from Gennum’s GS4911 clock generator directly to the GS1531’s PCLK input and configure the GS1531’s loop bandwidth accordingly.Key
