Manufacturer:HIT Description:Frequency Mode Select. This three-level input selects the frequency range for the clock and data recovery Receive PLL and the frequency multiplier Transmit PLL. When this input is held HIGH the two PLLs operate at the SONET (SDH) STS-3 (STM-1) line rate of 155.52 MHz. When this input is held LOW the two PLLs operate at the SONET STS-1 line rate of 51.84 MHz. The REFCLK frequency in both operating modes is 1/8 the PLL operating frequency. When the MODE input is left floating or held at VCC/2 the TSER inputs substitute for the internal PLL VCO for use in factory testing. |
