All SONET jitter requirements are met, including: Jitter Transfer; Jitter Generation; and Jitter Tolerance.
All specifications are quoted for -40 to 85C ambient temperature unless otherwise noted.
The device is intended for WDM system applications and can be used with either an external reference clock or an on-chip oscillator crystal.
Both native rates and 15/14 rate digital ‘wrappers’ rates are supported by the ADN2809, without any change of reference clock required.
This device together with a PIN diode and a TIA preamplifier can implement a highly integrated, low cost, low power fiber optic receiver.
The receiver front end Signal Detect circuit indicates when the input signal level has fallen below a user adjustable threshold.
The ADN2809 is available in a compact 48 pin chip scale package.
