- Number of taps
- 9 physical taps standard with four time-domain mapped taps depending on the data rate.
- Operating data rate range
- LE160, 4 Gb/s to 21 Gb/s
LE320, 8 Gb/s to 32 Gb/s 1
1 Operation down to 8 Gbps is supported with single tap response.
- Coupling
- AC coupled
- Maximum data input level
- 800 mvp-p (typical)
- The maximum input signal level acceptable to the data input for proper operation. Not the input damage level.
- Data input sensitivity
- 40 mVp-p, (typical)
The minimum input signal level acceptable to the data input for proper operation
- Data input termination
- 100 Ω differential
50 Ω single-ended
- Connector type
- 2.92 mm female
- Input return loss
- (typical)
- LE160
- 10 dB RL 0.2 to 7 GHz
5 dB RL > 7 GHz to 30 GHz
- LE320
- 10 dB RL 0.2 to 7 GHz
5 dB RL > 7 GHz to 30 GHz
DATA OUTPUT (DIFFERENTIAL)
- Minimum settable amplitude range (DP/DN)
- 0 mVp-p to 2000 mVp-p maximum differential
Pattern: 1100, taps set for flat loss
- Settable amplitude resolution
- 0.15 dB (typical)
- Coupling
- AC coupled
Skew between DP and DN - <2 ps (typical), 4 ps (specified), taps set for flat frequency response
- Additive random jitter
- LE160
- 220 fsRMS (typical), input pattern 1100 1
- LE320
- 300 fsRMS (typical), input pattern 1100 1
1 Additive Jitter. The LE320/LE160 can be configured to many conditions resulting in increased Data Dependent Jitter (DDJ) and Random Jitter (Rj), for example in a backplane emulation configuration. The LE320 can be tuned to have < 300 fs RJ RMS and < 6 ps of DDJ.
- Tap range
- -63 to +63 tap settings
- Tap resolution
- 1.6%, any tap
- Connector type

- Zero output state timing constant
- ±600 mV, single ended signaling level to 0 V ±10 mV in ≤ 40 UI = 2.9 ns; idle state (fall time after enable asserted)
- Consecutive run length amplitude droop
- <10 % maximum droop (typical)
