Epoch successfully completed development of phase lock loop with digital phase detector and digital loop filter for Epoch customer.
This was achieved thanks to extensive use Epoch silicon proven bulding level silicon IPs. For this project the digital phase detector, loop filter, and digital to analog converter were custom designed.
Fractional-N PLL with time-to-digital based phase detector and VCO auto-band calibration.
Internal programmable modulations for automotive radar Implements delta-sigma noise cancellation and 2-point modulation integrated bandgap reference, and voltage regulators.
Epoch has achieved 1st pass functional success with the analog phase lock loop for application in automotive radar.
This was achieved thanks to heavy use of Epoch's silicon proven schematic IP. VCO and dividers were customized to the automotive radar Frequency range of operation and only the ramp generator was custom designed.
