The CS61535A combines the complete analog transmit-and-receive line interface for T1 or E1 applications in a low-power, 28-pin device operating from a 5 V supply.

The device features a transmitter jitter attenuator, making it ideal for use in asynchronous multiplexer systems with gapped transmit clocks. The CS61535A provides a matched, constant impedance output stage to ensure signal quality on mismatched, poorly terminated lines.

The device uses a digital DLL (delay-locked loop) clock and data recovery circuit, which is continuously calibrated from a crystal reference to provide excellent stability and jitter tolerance.


  • Provides analog pulse code modulation (PCM) line interface for T1/ E1 applications
  • Provides line driver and data/clock recovery functions
  • Transmit side jitter attenuation starting at 6 Hz with >300 UI of jitter tolerance
  • B8ZS/HDB3/AMI encoders/decoders
  • 14 dB of transmitter return loss
  • Compatible with SONET, M13, CCITT G.742 and other asynchronous muxes
  • Low-power consumption (typically 175 mW)
  • Package: 28-pin PLCC; lead-free assembly
