ZHCSIF5G December 2015 – July 2024 TPS99000-Q1
PRODUCTION DATA
The following signals are analog inputs to TPS99000-Q1. Most of these analog inputs are DC levels and are somewhat insensitive to noise, but others are part of the real-time color control algorithm of the TPS99000-Q1 and therefore must be kept immune from noise injection from other signals. The list of analog input pins is as follows:
PIN | NAME | SIGNAL TYPE |
---|---|---|
70 | TIA_PD2 | Real-time |
73 | TIA_PD1 | Real-time |
82 | LS_SENSE_N | Real-time |
83 | LS_SENSE_P | Real-time |
85 | ADC_IN1 | Real-time |
86 | ADC_IN2 | DC |
88 | ADC_IN3 | DC |
90 | ADC_IN4 | DC |
92 | ADC_IN5 | DC |
93 | ADC_IN6 | DC |
94 | ADC_IN7 | DC |
96 | V3P3V | DC |
97 | V1P8V | DC |
98 | V1P1V | DC |
In particular, the photodiode inputs TIA_PD1 and TIA_PD2 are especially sensitive to noise as they are inputs to very high gain amplifiers. It is recommended to shield these signals from noise with a ground trace next to the signal.
